Two angles are complementary when they add up to 90 degrees<span>
m</span>∠B = 90° - m∠A = 90° - 40° = 50°
Two angles are supplementary when they add up to 180 degrees
m∠C = 180° - m∠B = 180° - 50° = 130°
Answer:
The answer is C
Step-by-step explanation:
Answer:
a = 1
b = -3
c = -2
Step-by-step explanation:
95% * x = 95
95/100 * x = 95
0,95 * x = 95
0,95x = 95 / : 0,95
x = 100
