Answer:
The measure of angle C = 92°
Step-by-step explanation:
The sum of opposite angles of cyclic quadrilateral is 180°
From the figure we can see that,quadrilateral ABCD is inscribed in a circle.
To find the value of x
m<B + m<D = 180°
(x + 10 ) + ( x + 24 ) = 180
x + 10 + x + 24 = 180
2x + 34 = 180
2x = 180 - 34 = 146
x = 146/2 = 73
To find the measure of <A
m<A = x + 15
x = 73
m<A = 73 + 15 = 88°
To find the measure of <C
m<C + m<A = 180°
m<C + 88 = 180
m<C = 180 - 88 = 92°
Therefore the measure of angle C = 92°
