Question

What is true about the figure?

In the figure, angles C and D are a
Therefore, angle C must measure
B = ?
C = ?
A = ?
D = 124°

Answer 1

<A = 56degrees

<B = 34degrees

<C = 56degrees

Explanation:

From tyhe diagram, the sum of m<C and m<D is 180degrees. Hence;

<C + <D = 180

<C + 124 = 180

<C = 180 - 124

<C = 56degrees

Also;

<B + 90 + <C = 180

<B + 90 + 56 = 180

<B + 146 = 180

<B = 180 - 146

<B = 34degrees

Similarly;

<A + <B = 90

<A + 34 = 90

<A = 90 - 34

<A = 56degrees
