Lets write this out:-

10² + 4 × 9 - 2³

Solve:-

10² = 10 × 10 = 100
100 + 4 × 9 - 2³
2³ = 2 × 2 × 2 = 8
100 + 4 × 9 - 8
4 × 9 = 36
100 + 36 - 8
100 + 36 = 136
136 - 8 = 128

10² + 4 × 9 - 2³ = 128

Good luck! :P

10^2 + 4\times 9 -2^3

First take care of all the exponents.

100 + 4 \times 9 - 8

Now do the multiplication.

100 + 36 - 8

Now add and subtract from left to right.

136 - 8

128

Your final answer is 128.

A 45 foot ladders leaning up against a building. The base of the latter is 20 feet away from the building. What is the angle of
Tatiana [17]

Answer:

The angle of elevation to the top of the building is 63.61 degrees

Step-by-step explanation:

Here, we want to calculate angle of elevation to the top of the building.

For this, we need a triangle

Please check for this in the attachment.

From the diagram, we are to calculate the angle theta.

To do this, we use trigonometric identities.

Looking at what we have, we have the hypotenuse and the adjacent.

So the trigonometric identity to use is the cosine

Mathematically Cosine theta = adjacent/hypotenuse

Thus, Cos theta = 20/45

Cos theta = 0.444444444444444

Theta = Arc cos(0.444444444444444)

Theta = 63.61 degrees
