Answer:
95°
Step-by-step explanation:
The sum of interior angles in a pentagon is 540°
100° + 145° + 120° + 80° + x = 540°
445° + x = 540°
x = 95°
Answer: 41 degrees
measure of angles in a triangle is 180 degrees
So
87 + 52 + ? = 180
139 + ? = 180
? = 41
6
The 3 by 2 rectangle is 6 so 15-6=9
3 x (x-2) x 0.5 = 9
3 x (6-2=4) 4 = 12 / 2 = 6
