Answer:
9
Step-by-step explanation:
Assume that the measure of the angle is x
That would mean that the compliment of that angle would be 9x
Two angles are complementary when their sum equals 90
That means x + 9x equals 90.
We can combine x and 9x into 10x, leaving us with 10x=90
Divide both sides by 10
x=9
Answer:
60
Step-by-step explanation:
The sum of the angles of a triangle is 180
x+x+x = 180
3x= 180
Divide by 3
3x/3=180/3
x = 60
20 times the square root of 10
Answer:
24
Step-by-step explanation:
0.2 * 120 = 24
also, 120% of 20 = 24
