Easey peasy
oposite angle is equal
other angles are supplementary (supplementary means add to 180, and a straight line=180 so if you look at 2 lines intersecting and think for a little bit, you wiill see why)
oposite angle=30
other angle is adds to 180
30+other=180
subtract 30
other=150
other is oposite other other
other=other other
150=other other
angles are
150,30,150
Answer:
False, True, True are thr answers
Answer:
Angle D= 140
Step-by-step explanation:
7x+7x+ 4x+4x+7x+7x= 720
36x=720
x= 20
Area of Trapezoid = h(b1+b2/2)
b1 and b2 are the lengths of each base and h is the height.
Area = 16(20+24/2)=352 Square Feet
352/20=17.6 Cans of paint.
Hope this helps and is correct, I haven't done this kind of math in a while.
