Question

If two angles are complementary, which is the sum of their measurements?

A. 45o

B. 90o

C. 120o

D. 180o

Answer 1

Answer: a complimentary angle measures 90 degrees. The measure of 2 complimentary angles would be 2x90=180

Explanation:

Answer 2

`90^(\circ)`

Explanation:

An angle is a figure obtained by two rays sharing a common vertex .

Here, a ray is a line with only one end point .

A line segment is a line which has two end points .

Vertex is a point where the two lines meet .

Two angles
`\alpha` and
`\beta` are said to be complementary if
`\alpha +\beta` =
`90^(\circ)` .

{ For example if we take
`\alpha`=
`40^(\circ)` then it's complement is
`\beta` =
`50^(\circ)` as
`\alpha +\beta =40^(\circ)+50^(\circ)=90^(\circ)` }

So, we can say if two angles are complementary then their sum is
`90^(\circ)` .

Option B. is correct .
