The 3 angles need to equal 180
The middle angle is given as 100.
180 -100 = 80
There is an x on each side so you have 2x
2x = 80
X = 80/2
X = 40 degrees
Answer:
Each x should equal 40
Step-by-step explanation:
The total is equal to 180°. You already know that you have 100°. Then if you subtract 100° from 180° you will get 80°. Since you have two “x” you need to divide 80° by two and you’ll get 40°
a² + b² + c² ≠ ab + bc + ca
a right angle (90 degrees)
20-12=8
8 divided by 75= 72
