Answer:
True
Step-by-step explanation:
Hope this helps! :)
The top number of the fraction indicates how much the line rises and the bottom of the fraction indicates how much to the right it moves. Start at the bottom left and move up one Space then 4 to the right. This is your first point. From there move up one space and 4 to the right again. Repeat and draw line through dots.
The 2 angles are complementary angles and need to equal 90 degrees.
Making an equation we have:
4x-10 + x = 90 degrees
Add like tems:
4x +x = 5x
Now we have:
5x-10 = 90
Add 10 to both sides:
5x = 100
Divide both sides by 5:
x = 100/5
X = 20
