Answer:
x=23
Step-by-step explanation:
The first triangle has two sides that are the same, therefore the two bottom angles are the same as well, so the two bottom angles equal to 56 degrees of the total 180 degrees that a triangle should have. That leaves the last angle to be 124 degrees.
Now what you do is subtract 9 from 124 to get 115
Lastly divide 115 by 5 to get 23.
