Question

Find the value of x .

Answer 1

x=34

Explanation:

First, we know that the other angle on the bottom left is supplementary to 121, so the two add up to 180.

180-121=59

So, the two bottom angles are 59 and 87

All the angles in a triangle must add up to 180

59+87+x=180

146+x=180

Subtract 146 from both sides

x=34

Hope this helps! :)

Answer 2

Answer: 34

Step-by-step explanation: 121 is the angle outside. 121 plus the other angle must equal 180 because it is a straight angle. So that angle is 59. All triangles angles add up to 180. 59 plus 87 equals 146. 180-146 is 34.
