Two complementary angles sum is 90 degrees.
Angle 1 = x
Angle 2 = 2x ( two times angle 1)
Equation: x + 2x = 90
Solve:
Combine like terms:
3x = 90
Divide both sides by 3:
X = 90/3
X = 30
Angle 1= 30
Angle 2 = 60
Answer:
B. 24
Step-by-step explanation:
The way to find range is by putting the set from largest to smallest, then subtracting the highest number from the lowest. In this case, the highest number would be 31, and the lowest would be 7. So 31-7=24 which is your range. Hope this helps! (please give brainlist!) :)
if your asking for the equation, it's t + 7 < 3
3 out of 10 or 30% becasue if he is guessing and he has to get 7 out of 10 right then it would be 3 out of 10
