Question

Please help me out here friends.. :(

Answer 1

Answer:

Ans 12= 35° and Ans 13= 30°

Step-by-step explanation:

Answer of question number 12:

We know that sum of co-interior angles is equal to 180°.

4x° + (x+5°)= 180°

4x° + x + 5°= 180°

5x° + 5°= 180°

5x°= 180° - 5°

x= 175°/ 5

x= 35°

Answer of question number 13:

We know that corresponding angles are equal.

So, (4y + 8)° = (5y - 22)°

4y° + 8° = 5y° - 22°

8° + 22° = 5y° - 4y°

30° = y

y= 30°

Here is your answer dear.
