Question

What is the value of x in the figure shown below​

Answer 1

Given,

AB=5 cm,BC=12 cm

So, AC=

5

2

+12

2

=13

We know that

x=

2

AB+BC−AC

x=

2

5+12−13

x=

2

4

x=2 cm

Hence, this is the answer.

Answer 2

x = 68

Explanation:

The consecutive angles of a parallelogram are supplementary, sum to 180° , then

69 + 43 + x = 180 , that is

112 + x = 180 ( subtract 112 from both sides )

x = 68
