Answer:
x = 98
Step-by-step explanation:
First we need to find out what the last angle of the triangle is equal.
First we add 53 + 45 = 98
Now we subtract 180 - 98 = 82
We subtract 180 because all triangle MUST equal 180.
Ok so the last angle of the triangle equals 82. To confirm we can add them all up. 53 + 45 + 82 = 180 so we know that it is correct.
Now we can find the value of x. So we know that 82(the angle of the triangle we just did) and x have to equal 180 because all lines equal 180.
so we add 180 - 82 = 98 so x = 98
To make sure we can add x or 98 + 82 = 180
Hope this made sence, an hope it helped!! :)
