Answer:32?
Step-by-step explanation:
You’re going to want to use the pythagorean theorem (a^2+b^2=c^2). Start with what you know your hypotenuse is 53 ft (c) and one of your sides is 45 ft (a). Plug in the equation: (45^2+b^2=53^2). Next square each side: (2025+b^2=2809). Then: (b^2=784). Finally square root: (b=28) So your answer is x=28 ft.
Answer:
If C is 5 and B is 7 the a is 9
Answer:
Right angles is 90° so 90°+30°=120°.A straight line is 180°. So you do 180°-120° which is 60. So A=60°
