Question

Please help me on these problems, I don’t understand this.

Answer 1

6. x = 60°

7. x = 118°

8. x = 27°

Explanation:

We know that the sum of angles of a triangle is 180° , so by using that we can find out the value of x .

6. x°+ 90°+30° = 180°

=> x° = 180°-120°

=> x° = 60°

7. x°+33°+29° = 180°

=> x°= 180°-62°

=> x° = 118°

8. x°+132°+21° = 180°

=> x° = 180°- 153°

=> x° = 27°

Answer 2

6. x= 60

7. x = 118

8. x=27

Explanation:

The sum of the angles of a triangle is 180

6. The box in the corner is a right angle which is 90 degrees

x+90+30 = 180

Combine like terms.

x +120 = 180

x = 180-120

x = 60

7. x+33 + 29 = 180

Combine like terms.

x+62=180

x = 180-62

x=118

8. 21+132+x = 180

Combine like terms

153+x = 180

x = 180-153

x=27
