Answer:
67.5°, 107.5°
Step-by-step explanation:
For supplementary angles, their sum equals 180°.
Let x be the first angle and y be the second angle, then
x + y = 180°.
It is given that x = y + 45°.
So x + y = 180°
substituting x into the equation, we have
y + 45° + y = 180°
simplifying, we have
2y + 45° = 180°
collecting like terms, we have
2y = 180° - 45°
2y = 135°
dividing through by 2, we have
y = 135°/2
y = 67.5°
Since y = 67.5°
then x = y + 45°
x = 67.5° + 45°
x = 107.5°

Answer:
5x + 11
Explanation:
3(x + 7) + 2x − 10
<u>Distribute</u>
(3)(x) + (3)(7) + 2x − 10
3x + 21 + 2x − 10
<u>Combine Like Terms</u>
3x + 21 + 2x − 10
(3x + 2x) + (21 − 10)
= 5x + 11
