There are 12 months in a year so you times 525 by 12
<u>Extending</u> one <u>side</u> of the given <u>triangle</u> one more <u>angle</u> can be obtained.
An exterior angle is the angle between any side of a shape, and a line extended from the next side.
The remote interior angles are the two angles inside the triangle that do not share a vertex with the exterior angle.
An adjacent interior angle to the exterior angle is the angle that together with this exterior angle are supplementary (when they add up to 180°).
Two angles are complementary when they add up to 90°.
Extending one side of a triangle you get exterior angle.
Answer: correct choice is C
The answer is -49 because you multiply by 7.
Answer:
y = 11
Step-by-step explanation:
We use the definition of Supplementary Angles and Adjacent Angles.
Step 1: Set up equation 1 (Definition of Supplementary Angles)
5x - 4 +7x - 8 = 180
Step 2: Solve for <em>x</em>
12x - 4 - 8 = 180
12x - 12 = 180
12x = 192
x = 16
Step 3: Plug in <em>x</em>
5(16) - 4
80 - 4
76°
Step 4: Set up equation 2 (Definition of Supplementary Angles)
76 + 9y + 5 = 180
Step 5: Solve for <em>y</em>
9y + 81 = 180
9y = 99
y = 11
