Answer: The height of the building is 50.75 feet.
Step-by-step explanation:
The ratio between the height of the object and the casted shadow must be equal for all the objects, as the angle at which the source if light impacts them is the same.
For the person, we know that it is 5.8ft tall, and the shadow is 3.2ft long.
The ratio will be: 5.8ft/3.2ft = 1.8125
Now, if H is the height of the building, and the shadow that the building casts is 28ft, we must have:
H/28ft = 1.8125
Now we can solve this for H.
H = 1.8125*28ft = 50.75 ft
Then the height of the building is 50.75 feet.
Answer:
∠B = 54 °
Step-by-step explanation:
If sum of two angles add up to 180°, then the two angles are called supplementary.
m∠A + m ∠B = 180°
7x + 7 + 4x - 14 = 180
7x + 4x + 7 - 14 = 180
11x - 7 = 180
11x = 180 + 7
11x = 187
x = 187 ÷ 11
m∠B = 4x - 14
= 4*17 - 14
= 68 - 14
Answer:
The correct option is D
Step-by-step explanation:
The correct option is D.
They both have the same height, assuming that each coin has same volume, then how can coins in 1 stack have different volume than coins in another stack no matter how you stack them.
Like two cylinders with same base area and height have same volume. Like wise rectangle and parallelogram with same base and same perpendicular height having same area....
The other person is literally wrong. The answer is D. Supplementary because two angles that add up to 180 are supplementary angles.
