X=45
We already know that one angles is 90 degrees and that the full degrees inside a triangle is 180
So minus 90 from 180 and you get 90.
Since the other two angles are congruent that means they have the same measure so divide 90 by 2 to get the measure of both angles which is your answer

Step-by-step explanation:
The elements found in greatest abundance in the Earth include oxygen, silicon, aluminum, iron and calcium; these substances also make up the bulk of the moon. Although the moon is a<span>n airless world, it has large amounts of oxygen in the form of solid chemical compounds.</span>
Isolate the x. Root both sides
√x²< √81
x < 9 is your answer

A-4=B
2+C=B
A+B+C=13
A=b+4
C=B-2
Plug in to equation 3
(B+4)+B+(B-2)=13
Rearrange
B=11/3
A=(11/3)+4= 23/3
C=(11/4)-2= 3/4
