The 3 inside angles of a triangle need to equal 180 degrees.
Since you are given 2 angles, subtract both of those from 180 to find X.
X = 180 - 70 - 30 = 80 degrees.
X = 80
Answer:
Call the number we need to find a.
Inequality: (12 + a) ÷ 2 < 27
<=> 12 + a < 54
<=> a < 54 - 12
<=> a < 42
Answer:
22
Step-by-step explanation:
x + 90 + 68 = 180
x + 158 = 180
x = 22
Answer:
B
Step-by-step explanation:
d+c=180 because 360 degrees are in the parrallegram so divide that by 2 so 114+c=180 so
c=66
