Question

Q13. The angle (x-10)° and (190-x)"
are:
Complementary
corresponding angles
vertically opposite
Supplementary​

Answer 1

Answer:

Supplementary

Step-by-step explanation:

(x-10) + (190-x) = 180

x-10+190-x = 180

x-x-10+190 = 180

180 = 180

Hence proved that they are supplementary.

Answer 2

Answer:

180=180

LHS =RHS

Step-by-step explanation:

(X-10)+(190-X)=180

180 IS THE SUM OF TWOSUPPLEMENTRY ANGLE IS 180

SO

190-10=180

180 =180

LHS = RHS
