Answer:
x = 20
4x = 80°
5x = 100°
Step-by-step explanation:
The given angles are supplementary so their sum is 180°
4x + 5x = 180
9x = 180 divide both sides by 9
x = 20
The value of the angle marked 4x = 4 × 20 = 80°
The value of the angle marked 5x = 5 × 20 = 100°
(5x7)-9 Thisis because product means multiply "Of" mean sa smaller equation. therefor you need the (...) then 9 less than is minus but it has to go after the product since it's subtraction
Answer:
A Variable that you feel comfortable with whether it is A,B,C, or X,Y,Z.
I choose S

A: meaning area
X: meaning sides
All your doing is multiplying side by side, Not all sides, Just 2 sides
You need to add them all up
