Question

The following figure is not drawn to scale.

Answer 1

1) The sum of all the angles in a triangle is always 180 degrees, so to find x, you can set up an equation with the provided angles and solve.

45+60+x=180

105+x=180

x=75

2. x degrees and y degrees add up to 180 degrees, because they form a straight angle, which is a straight line. You can set up an equation using the value of x you found in the previous part and solve for y.

x+y=180

75+y=180

y=105
