1. In a parallelogram ABCD, AD=12cm. if the altitudes corresponding
to sides AB and AD are respectively 8cm and 7cm find AB.
​

Answers

Answer 1

Answer:

10.5 cm

Step-by-step explanation:

area of parallelogram = Bh

12 x 7 = AB x 8

AB = 12x7 / 8 = 21/2 = 10.5

Always

Answer:

always,sometimes,never,always

Step-by-step explanation:

Equilateral triangles are  

always

acute triangles. Yes, because acute is always 60 degrees, and equilateral is basically your average triangle, so its corners have 60 degrees.

Scalene triangles are  

sometimes

acute triangles.      Scalene triangles always dont have that sharp corner..they sometimes do, the sharp turn which is 60 degrees, ACUTE IS ALWAYS 60 DEGREES.

Right triangles are  

never

acute triangles. A right angle cant be a acute, not 60 degrees..

Obtuse triangles are  

always  

isosceles triangles.  Isosceles means atleast 2 of the sides look the same, i included how to recognize obtuse, right,etc

i suggest look up a number chart similar to that and place the (4,4) on it

Step-by-step explanation:

im sorry if i couldnt help

Answer:

m is the slope, so it has a slope of 1. it gave you a point so it wants you to plug the point and slope into point-slope form and then solve for the equation to be in slope-intercept form so you can graph it.

point-slope form is: y -y1 = m(x -x1)

plug in the given values and solve

y - 4 = 1(x -4) (use the distributive property to get rid of the parenthesis)

y -4 = 1x - 4 (add 4 to both sides to isolate y)

y = 1x  (1x is the same as x, so it's redundant to write 1x)

y= x (this is the equation of the line)

if you don't know how to graph y=x, whatever the y value is, the y value is. it's a straight line going through the origin.

A roofer leaned a 16-foot ladder against a house. If the base of the ladder is 5 feet from the house, how high up the house does the ladder reach?

Answers

Answer:

15.20feet

Step-by-step explanation:

Length of the ladder = 16foot (hypotenuse)

BAse of the ladder from the house = 5feet (adjacent)

height of the house = x (opposite)

Using the pythagoras theorem

hyp^2 = opp^2 + adj^2

16^2 = 5^2 + opp^2

256 = 25 + opp^2

opp^2 = 256-25

opp^2 = 231

opp =√231

opp = 15.20

Hence the house is 15.20feet high up the house

Answers

Answer:

L.H.S. = [tex]\frac{1}{cosx} -\frac{sinx}{cosx}sinx[/tex]

= [tex]\frac{1}{cosx} - \frac{sin^2x}{cosx}[/tex]

= [tex]\frac{1-sin^x}{cosx} = \frac{cos^2x}{cos x}[/tex]

= cos x = 1/secx

Step-by-step explanation:

Hey there!

Given;

sec x - tan x . sin x = 1/(sec x).

~ Taking LHS.

= sec x - tan x . sin x

= 1/(cos x) - (sin x/cos x) . sin x { Using formula sec x = 1/cos x and tan x = (sin x/cos x)}

~ Multiply (sin x) and (sin x).

[tex] = \frac{1 - { (\sin(x) )}^{2} }{ \cos(x) } [/tex]

~ Use formula 1-sin²x= cos²x

[tex] = \frac{ {cos}^{2} x}{ \cos(x) } [/tex]

~ Cancel cos x.

= cos x

= 1/sec x { cos x = 1/sec x}

→ RHS proved.

He stood for a moment, his lean, drawn face haggard in the light of the two hurtling moons.He looked hopelessly across the dark spaceport. It was a large one, for this ancient town of Syrtis was the main port of Mars. The forked light of the flying moons showed many ships docked on the tarmaca big liner, several freighters, a small, shining cruiser and other small craft. And for lack of one of those ships, his hopes were ruined!A squat, brawny figure in shapeless space-jacket came to Kenniston's side. It was Holk Or, the Jovian who had been waiting for him."What luck?" asked the Jovian in a rumbling whisper."It's hopeless," Kenniston answered heavily. "There isn't a small cruiser to be had at any price. The meteor-miners buy up all small ships here.""The devil!" muttered Holk Or, dismayed. "What are we going to do? Go on to Earth and get a cruiser there?""We can't do that," Kenniston answered. "You know we've got to get back to that asteroid within two weeks. We've got to get a ship here."Desperation made Kenniston's voice taut. His lean, hard face was bleak with knowledge of disastrous failure.The big Jovian scratched his head. In the shifting moonlight his battered green face expressed ignorant perplexity as he stared across the busy spaceport."That shiny little cruiser there would be just the thing," Holk Or muttered, looking at the gleaming, torpedo-shaped craft nearby. "It would hold all the stuff we've got to take; and with robot controls we two could run it.""We haven't a chance to get that craft," Kenniston told him. "I found out that it's under charter to a bunch of rich Earth youngsters who came out here in it for a pleasure cruise. A girl named Loring, heiress to Loring Radium, is the head of the party."The Jovian swore. "Just the ship we need, and a lot of spoiled kids are using it for thrill-hunting!"Kenniston had an idea. "It might be," he said slowly, "that they're tired of the cruise by this time and would sell us the craft. I think I'll go up to the Terra Hotel and see this Loring girl.""Sure, let's try it anyway," Holk Or agreed.With the Jovian clumping along beside him, Kenniston made his way from the spaceport across the ancient Martian city.Read the following line from the text:He stood for a moment, his lean, drawn face haggard in the light of the two hurtling moons.Select the correct meaning of the word haggard.
