Answer:
Step-by-step explanation:
<em>Complementary angles sum up to 90°</em>
<u>Given</u>
<u>Substituting P in the first equation</u>
- 2M + 3° + M = 90°
- 3M = 87°
- M = 29°
<u>Then </u>
The two angles form a right triangle which is 90 degrees.
Add the two to equal 90:
3x-8 + 4x = 90
simplify:
7x-8 = 90
Add 8 to both sides:
7x = 98
Divide both sides by 7:
x = 14
A triangles is 180 degrees. 100+50=150.
180-150=30
X=30
