Answer:
the answer is 20
Step-by-step explanation:
180+180=360
80+70=150
180-150=20
It's the first one, an algebraic expression contains variables
Distance between Brad and bombs falling location we need
- Hypotenuse=H=41m
- Perpendicular=P=40m
Base be B
Apply Pythagorean theorem
- B²=H²-P²
- B²=41²-40²
- B²=9²
- B=9m
The answer is 4 feet.
Draw a line segment from D perpendicular to AC and intersect AC at F.
triangle ADF is a right triangle, with angle AFD=90, Angle DAF=half of BAC=30
in a 30-60-90 triangle, the shortest side is half of the hypotenuse. the hypotenuse AD=8, so DF=4
Draw a line segment perpendicular from D to AB and intercept AB at E.
DE is also 4 feet, same as above.
'is' in mathematics means the equal sign
'of' in mathematics means the multiplication sign
the number can be any variable you chose it to be

Divide both sides by 28

Multiply by 100 on both sides to isolate 'x'
14 is 28% of 200
