Find the measure of angle x in the figure below:
a: 35
b: 48
c: 69
d: 78

The best way to solve for x is to first solve for y and then subtract values. The top of "line" of the 3 angles togethers add up to 180 degrees. So from this, you can deduct this equation into . To solve for y, subtract and from the left hand side and rights hand side of the equation. now you know the value is . So the value of y is 69 degrees. 
Now you know two angles of a triangle and the sum of the angles in a triangle is 180 degrees. So the equation is . To solve for x, subtract from both sides. . So you know that degrees.

3.6,

4.5,

Step-by-step explanation:

it depends on what is the base and what is the height. it does not say.

hope this helps:)
