Quadrilateral abcd is inscribed in a circle.

what is the measure of angle a?

enter your answer in the box.

m∠a= °

133

Step-by-step explanation:

Given is a cyclic quadrilateral ABCD.

We know that in a cyclic quadrilateral, opposite angles are supplementary.

A+C =180

Given that A = 4x+5 and C = x+15

Add these and equate to 180

Verify:

When x= 32, Angle C = 47

A+C = 133+47 = 180

Hence right answer

its kind of blurry. can you put a clearer pic?

step-by-step explanation:

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1
