Question

how to solve for x please​

Answer 1

Answer:

24°

Step-by-step explanation:

we know that in a circle angle at the center is twice the angle at its circumference

so in given figure

angle C = 1/2 angle O

angle C = (2x + 28)/2

angle C = x + 14

ABCD is a cyclic quadrilateral

we have

angle C + angle D = 180°

(x + 14) + 3x - 70 = 180°

4x + 84 = 180°

4x = 180 - 84

4x = 96°

x = 24°
