First find the area of the rectangle.

Area of Rectangle= Lenght×Width
Area of Rectangle=10×5
Area of Rectangle =50cm^2

Then you find the area of the triangle.

Area of Triangle= Length×Height
Area of Triangle=8×5
Area of Triangle=40cm^2

Add the two areas to find the area of the whole figure.

50 + 40 = 90cm^2

How is a greater number a factor of a smaller number?

Eduardwww [97]

Explanation:

It depends on the definition of "factor" that you use.

One dictionary defines "factor" to be ...

"a number or quantity that when multiplied with another produces a given number or expression"

In that sense, 7 can be a factor of 3, because 7 × (3/7) = 3.

___

Often we use the term "factor" when we mean "integer divisor", or "positive integer divisor". Using this last definition, the only factors of 3 are 1 and 3.

Other times, we use the term "factor" to mean "prime factor." By this definition, the only factor of 3 is 3 itself.

A person is standing 50 ft from a statue. The person looks up at an angle of elevation of 8 degrees when staring at the top of t

borishaifa [10]

The height of the statue is 19.5 feet.

Why?

We can solve the problem using trigonometric formulas. In this case, we are going to use the trigonometric formula of the tangent.

We know that the person is standing 50ft from the statue, so, it will be the base of the two triangles formed by both angles (elevation and depression)

Using the trignometric formula, we have:

First triangle:

$tg(\alpha )=\frac{h_{1}}{base} \\\\tg(8\°)=\frac{h_{1}}{50ft}\\\\0.14*50ft=h_1\\\\h_1=7ft$

Second triangle:

$tg(\alpha )=\frac{h_{2}}{base} \\\\tg(14\°)=\frac{h_{1}}{50ft}\\\\0.25*50ft=h_1\\\\h_1=12.5ft$

Now, the total height of the statue will be:

$TotalHeight=h_1+h_2=7ft+12.5ft\\\\TotalHeight=19.5ft$

Have a nice day!
