Is this an example of complementary or supplementary angles?

That is an example of a supplementary angle

Step-by-step explanation:

Complementary angle are angles that sum up to 90°.

Supplementary angle are angles that sum up to 180°.

In the example provided, the x and 118° add up to 180° because of the straight line. If it was complementary, the total angle would look like an L shape

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
