Question

5.
x and 40° are a pair of complementary angles. Make an equation and
solve it to find the size of x.

6.
y and 125 are a pair of supplementary angles. Make an equation and
solve it to find the size of y.

7.
If a and 110° form a linear pair, find the size of a.

8.
If a and 65 are vertically opposite angles, find the size of a


May u help me☺️☺️☺️:):):)​

Answer 1

Answer:

5. 50°

6. 55°

7. 70°

8. 65°

Step-by-step explanation:

5. x + 40°=90°

x=90°- 40°

x=50°

6. y + 125°= 180°

y = 180°-125°

y = 55°

7. Linear pair form an angle of 180°.

a + 110° = 180°

a = 180°- 110°

a = 70°

8. Size of a will be 65° because vertically opposite angles are always equal.
