18 Geometry question: Use an algebraic equation to find the measure of each angle that is representative in terms of X
1 answer:
Answer:
12x - 28° = 116°
7x + 32° = 116°
Step-by-step explanation:
12x - 28° and 7x + 32° are vertical angles. Vertical angles are congruent.
Therefore, to find the measure of each angle, we have to set each equation equal to each other as follows:
12x - 28° = 7x + 32°
Collect like terms
12x - 7x = 28 + 32
5x = 60
Divide both sides by 5
5x/5 = 60/5
x = 12
✔️12x - 28°
Plug in the value of x
12(12) - 28
= 144 - 28
= 116°
✔️7x + 32°
7(12) + 32
= 84 + 32
= 116°

Answer:
2*2*2*2 = 16
Step-by-step explanation:
The equivalent of 2^4 = 2 x 2 x 2 x 2 (multiply 2 four times)
2/5+4/7=2
14/35+20/35=2
34/35=2
FALSE
so the rectangle must be a placeholder that is added
so 34/35+x=2
x=1 1/35 or 36/35
