Answer:

X in.

Step-by-step explanation:

Answer:

x = 6

Step-by-step explanation:

We use the Pythagorean theorem

a^2 + b^2 = c^2, here, x is a, x + 2 = b, and 10 is c

x = 6:

6^2 + (6 + 2)^2 = 10^2

36 + 8^2 = 100

26 + 64 = 100

100 = 100

x = 6

37. Calculate the value of c in the triangle below.

Answers

Answer:

c = 26 in the triangle below.

Step-by-step explanation:

Here use the Pythagorean Theorem which states that for a right triangle,

a² + b² = c².

So here we input the triangle values.

a² + b² = c²

10² + 24² = c²

100 + 576 = c²

c² = 676

c = 26.

Answer:

26 is the correct answer

Answer both of the questions please :<

Answers

Answer:

First one: 37.5

Second one: 108

Step-by-step explanation:

For the first one:

the figure shown is a triangle

The area of a triangle can be calculated using this formula

[tex]A=\frac{bh}{2}[/tex] where b = base length and h = height

The triangle shown has a height of 7.5 and a base length of 10

Using this information we plug in the values into the formula.

[tex]A=\frac{7.5*10}{2} \\7.5*10=75\\\frac{75}{2} =37.5\\[/tex]

Hence the area of the figure is 37.5 square units

For the second one.

The figure shown is a parallelogram with a height of 9 and a base length of 12

The area of a parallelogram can simply be calculated by multiplying the base length by the height

So area = 9 * 12

9 * 12 = 108

Hence the area of the figure is 108 square units

Answer:

The answer to the first one is 37.5

The answer to the second one is 108

A=bh=12·9=108

The tree in your friend's yard casts a shadow that is 27 feet long. Your friend is 5 feet tall and casts a shadow that is 4.5 feet long. What is the height of the tree?

Answers

Answer:

the tree is 30 ft tall

Step-by-step explanation:

27/x = 4.5/5

cross multiply

(4.5)(x) = (27)(5)

4.5x = 135

divide the entire equation by 4.5 to isolate x

135/4.5 = 30

x = 30

Answer:

30ft

Step-by-step explanation:

Proportion/ratio question

Tree : Your friend

27ft  :   4.5ft

?      :   5ft

Formula given divided by the original or missing value equivalent

g/o = 5/4.5 = 1.11111 multiplier

Then use multiplier for the tree given value.

27 x 1.111111 = 29.999997

(c) What is 0.36 expressed as a fraction in simplest form? (no line)

Answers

Answer:

I’m sorry if I’m wrong

Step-by-step explanation:

A) 0.36 with a line over both 36 means as a decimal the 36 repeats, so it would look like 0.363636

as a fraction it would be 36/99, divide both numbers by 9 to get 4/11

B) 0.36 with the line over the 6 means just the 6 repeats so it would look like 0.3666

as a fraction that would be 33/90 , divide both by 3 to get 11/30

C) 0.36 would be 36/100, divide both numbers by 4 to get 9/25

Write and solve an equation to find the value of X

Answers

Angles on a straight line add up to 180 degrees so

45 + 3x = 180
Subtract 45 from both sides to remove the 45 on the left

3x = 135
Then divide both sides by 3
x = 45

Answer is X = 45

Answer:

45 + 3x = 180

x = 45

Step-by-step explanation:

45 + 3x = 180

3x = 180 - 45

3x = 135

x = 135/3

so, x = 45
