What’s the rest of the qurstion?
Answer:
The elevation to the top of the building from the point on the ground where the shopper is standing is = 17.35°
Step-by-step explanation:
From the ΔABC
AB = height of the building = 250 feet
BC = 800 ft
Angle of elevation = 


= 0.3125
°
Therefore the elevation to the top of the building from the point on the ground where the shopper is standing is = 17.35°
The variable in this equation is b, therefore we have to calculate the value of b.
-38=2b+25-(-7b)
-38=2b+25+7b
2b+7b=-38-25
9b=-63
b=-63/9
b=-7
Answer: the value of the variable is b=-7
We can check it out this answer:
-38=2b+25-(-7b)
-38=2(-7)+25-(-7(-7))
-38=-14+25-49
-38=-38
Answer should be 3 I’m pretty sure
The large rectangle is 3 times 6 but theres two so its 2 x 3 x 6
the medium rectangle is 2 times 6 but again there is two so 2 x 2 x 6
the small rectangle is 2 times 3 and once more there is two so 2 x 2 x 3
