you would add 4x-3 to 6x-6 and equal it to 180° which is 6x+4x-6-3=180° which is 10x-9=180° then use inverse operation to solve it.
Answer: 18.9
Answer:
c
Step-by-step explanation:
the answer is 2
Volume=areabase times height
base=traignele
area=1/2 times base times height=1/2 times 10 times 12=60
height=20
volume=60 times 20=1200 cubic feet
2nd option
Answer:
106 ft
Step-by-step explanation:
Assuming the shadow is measured along horizontal ground.
tanθ =opp/adj = building height/shadow length
building height = shadow length(tanθ)
h = 61tan60
h = 105.65509...
