Answer:
x+75=180
x=180-75
x=105
Step-by-step explanation:
x and a are on a straight line
a straight line=180
so you add the x to a=180

<em>Explanation below</em>
Step-by-step explanation:
<u>Angles in a Triangle</u>
There are two basic relations of angles we need to recall:
- Supplementary angles add up to 180°
- Internal angles of a triangle add up to 180°
Note a, b, and c are the internal angles of the triangle. The angle c is what is needed to a+b to complete 180°, thus:
c = 180 - ( a + b )
Also, note c and d are supplementary angles. Again, c is what is needed to d to complete 180°, thus
c = 180 - d
From the two relations above, it follows that:
a + b = d

Explanation:
Both legs are the same length, as indicated by the tickmark.
- a =
- b =
- c = x
Use the pythagorean theorem to solve for x
