Question

It would be great if someone can help me, please. I have a huge bad grade in math and need help

Answer 1

problem one
x = 55

problem two
x = 60

Answer 2

use angle addition postulate:

---

1) angle (2x+10) and (x+5) are supplementary, meaning they add up to 180 degrees so

(2x+10)+(x+5)=180

3x+15=180

x=55

---

2) angle (x-30) and x are complementary, meaning they add up to 90 degrees

(x-30)+x=90

2x-30=90

x=60
