Answer:
θ ≈ 48.2°
Step-by-step explanation:
The trig function that relates the angle, adjacent side, and hypotenuse is ...
Cos = Adjacent/Hypotenuse
This tells you ...
cos(θ) = 6/9
The angle is found from the cosine value using the inverse cosine function.
θ = arccos(6/9) ≈ 48.2°
Angle A is about 48.2°.

Answers
Answer:
7% sales tax
Step-by-step explanation:
Given the following question:
Sales tax = $26.60
It costs $380 before tax
In order to find the answer, we simply find a random percentage of the original cost before tax.
[tex]\frac{7\times380}{100} =2660\div100=26.6=26.60[/tex]
7% sales tax rate.

i) How do you find the sum of the angle measures of any convex polygon?
ii) If the polygon is regular, how do you find the measure of each interior angle in the polygon?
iii) How do you find the sum of the exterior angle measures of any convex polygon?
iv) If the polygon is regular, how do you find the measure of each exterior angle in the polygon?
Answers
Answer:
1) The sum of interior angles of a convex polygon is equal to (n-2) × 180°, where 'n' is the number of sides of the polygon.
2) A regular polygon is a flat shape whose sides are all equal and whose angles are all equal. The formula for finding the sum of the measure of the interior angles is (n - 2) * 180. To find the measure of one interior angle, we take that formula and divide by the number of sides n: (n - 2) * 180 / n.
4) Irrespective of the number of sides of a regular polygon, the measure of each exterior angle is equal and the sum of the measure of all the exterior angles of the regular polygon is equal to 360°.

20. 135°
Step-by-step explanation:
16. angles opposite to each other are equal
17. 180 - 140 = 40
18. 90 - 40 = 50
19. 65 + 70 = 135
180 - 135 = 45
20. 145 + 80 = 225
360 - 225 = 135

2 people share 3 chocolate bars equally. Each chocolate bar is the same size.
About how much chocolate does each person get?
Answers
Answer:
1.5 Pieces
Step-by-step explanation:
If you divide 3 chocolate bars by 2 people it will evenly be distributed by 1.5
Answer:
Just divide it.
Step-by-step explanation:
Take each bar height as 10. There are 3 bars. So the total height is 30. But there is 2 persons, so dividing it will result 15. So according to this assumed answer, I will say you will have to do this :
Give one bar to each of them and the bar should be divided in half, provided that two parts should be there as well as both parts of it should be 5 in height.
So, the upper part was an assume. This time, you mentioned no heights, so I will do it with equation process.
(meaning of each variable)
people = x
chocolate bar = 3
2x ( since 2 people) = 3 ( three chocolate bars )
2x=3
x=3/2
x=1.5 ( one and half )

To convert celsius to Fahrenheit:
=》(0°C × 9/5) + 32 = 32°F
To convert Fahrenheit to celsius:
=》(32°F − 32) × 5/9 = 0°C
To convert kelvin to celsius:
=》 C = K - 273.15.
To convert Fahrenheit to kelvin :
=》°F = (K − 273.15) × 9/5 + 32.
Using these formulas,
1) 38°C
= (38°C × 9/5) + 32
= 100.4°F
2) 313 K
= 313K − 273.15
= 39.85°C
3) 85°F - 69°F
= 16° F ------> difference
In celsius :
= (16°F − 32) × 5/9 =
-8.889°C
4) At 3 p.m = 13°F
If temperature increases by 2°F,
At 5 p.m =》
13 + 4
= 17°F
5) 55°F - 5

In kelvin :
