Question

Use the information given in the following
figure to find :


(i) X
(ii) B and C.​

Answer 1

Answer:

1. x = 22°.
2. B = 48° ; C= 61°.

Step-by-step explanation:

• Given figure is a quadrilateral. So, sum of all the angles is 360°.

           3x-5 + 8x-15 + 2x+4 + 90° = 360°

           13x-16 + 90° = 360°

           13x - 16 = 270°

            13x = 286°

          x = 22°.

• B = 2x + 4

           = 2×22 + 4

           = 44 + 4

        B = 48°.

       C = 3x - 5

           = 66 - 5

          C = 61°.
