Question

Given the triangle below answer the following questions

Answer 1

Answer:

A. 81

B. 99

C. 129

Step-by-step explanation:

(1) The sum of all the value of the angles in a triangle is 180.

So x + 51 + 48 = 180 <=> x = 81

(2) The value of the angle of the straight line is 180.

So x + y = 180 <=> 81 + y = 180 => y = 99

Same thing with (2)

51 + z = 180 => z = 129

Answer 2

Sum 51 and 48 and extract it from 180 and it gives you X

Sum of 48 and 51 and it gives you Y

Extract 51 from 180 it gives you Z
