- All angles in a triangle add up to 180°
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify and set up</em>
x° + 90° + 57° = 180°
<u>Step 2: Solve for </u><em><u>x</u></em>
- [Addition] Combine like terms: x° + 147° = 180°
- [Subtraction Property of Equality] Subtract 147 on both sides: x° = 33°
Step-by-step explanation:
1/20-1/4 ×<1/5-2/5×
<h3>collection of like terms</h3>
1/20+1/5 <-2/5×-1/4×
<h3>= 1/4 <-13/20×</h3>
Let "a" represent the angle. Then its complement is (90-a). The complement is 39° more than the angle, so we have
(90-a) - a = 39
51 = 2a
25.5 = a
The measure of the angle is 25.5°; its complement is 64.5°.
