Question

Find the value of angle x in the figures given below:
Kindly explain briefly

Answer 1

I) x = 40, II) x = 60

Explanation:

I) 180 is total of triangle. We already have 100 so we can subtract to find possible amounts for x: 180 - 100 = 80. 80 is now what we have left. We have 2 separate sides still unknown with each representing x. 80/2 sides results in 40.

II) 180 - 110 makes 70, which is the amount on bottom left corner. 70 plus 50 is 120 which is the amount in triangle apart from x. 180 - 120 = x. x is 60
