Question

The angles of a triangle add up to 180 degrees. The second angle is 30 degrees larger than the smallest angle. The third angle is 4 times as big as the smallest angle. Find the measure of the smallest angle (in degrees)

Answer 1

Answer:

50

Step-by-step explanation:

first angle = x

second angle = x+30

third angle = 4x

x + (x+30) + 4x = 180

6x + 30 = 180

6x = 180 - 30

6x = 150

x = 150:6

x = 50
