Answer:
45°
Step-by-step explanation:
All angles in a triangle add up to 180°
180 - (90 + 45)
= 180 - 135
= 45
Therefore the missing angle is 45°
Answer:
x = 18
Step-by-step explanation:
Since that is a right angle, we know that the total degrees of the angle is 90 degrees.
1) Based off of that, you can form the equation: 3x + 2x = 90.
2) solve the equation for x. Combine like terms: 3x + 2x = 5x.
5x = 90
3) So now, divide both sides by 5. 90 / 5 = 18
x = 18
Therefore, the correct answer is x = 18.
You can move the variables to one side, so then:
-
(f to the power of 0 is 1, so we can discard that)
