Answer:
x = 10
Step-by-step explanation:
it has 8 sides so:
total interior angle degrees = (180° x 8 sides) - 360° = 1080°
11x + 14 + 4x + 87 +2x + 70 + 4x + 31 + x + 92 + 3x + 167 + 5x + 48 + 2x + 251 = 1080°
combine like terms:
32x + 760° = 1080°
subtract 760° from both sides of the equation:
32x = 320°
divide both sides by 32:
x = 10
For Question Number one
(2+10)²+4=148
Question Number two:
(6+5)×(8-6)=22
I mean, they both do. i am not 100% sure, but im pretty sure. Hope this helps!
The slope formula can be used to prove a triangle has
<span>a right angle
and slope formula also prove that lines are parallel
so i conclude option B is correct
hope it helps</span>
