nalin [4]

Answer:

X = 20.6 inches

Step-by-step explanation:

Pythagorean Theorem: A^{2} =B^{2} +C^{2}

A = 41.2 in, while B = 35.7 in and we are solving for C.

41.2^{2} = 35.7^{2} +C^{2}

1697.44 = 1274.49 + C^{2}

Now solve for C

422.95 = C^{2}

Take the square root

20.5657482237 = C

A man standing on the roof of a building 58.0 feet high looks down to the building next door. He finds the angle of depression t
aksik [14]
Check the picture below.

make sure your calculator is in Degree mode, since the angles are in degrees.

so "x" is about 25.15 or so, that simply means, the building are about 25 feet apart from each other.

notice, the smaller building is 50 - y in height.

and just a quick note, angle of depression means, the angle below the horizontal, or the angle going downwards from orientation.

This is another one yet do i not get? help!

Answer:

Rate of Interest is 20\%

Step-by-step explanation:

Given that

I=\$ 300, P=\$3000

and T=0.5 years

To find rate of interest

We have I=PRT

Therefore

R=\frac{I}{PT}\times 100

R=\frac{300}{(3000)(0.5)}\times 100

=\frac{1}{10(0.5)}\times 100

=20\%

Therefore R=20\%

Rate of Interest is 20\%
