Answer:

Sin, Cos, Tan and others are used to calculate the ratios of the sides of a right angled triangle by taking a certain angle as the angle of reference.

On the other hand, Sin‐¹, Cos‐¹ and Tan-¹ are used to find the reference angle used to calculate the ratio of sides.

For this question,

we need to find which option should used to calculate the angle the slide makes with the vertical support.

So the option will have to be either A, C or E.

here, the base is 2.81m and hypotenuse is 3.64m.

we know, Cos = base / hypotenuse

So the angle is given by Cos-¹(2.81/3.64)

Option C

2.terms: 5h^2, -3h^2, - 4h, 3h, 7       like terms: 5h^2 and -3h^2, - 4h and 3h

3. 3m + 6

4. 15b + 2

5. 3x + 9

Step-by-step explanation:

1. 4r + 2 - 6 +3r

  terms: 4r, 2, -6, and 3r                     like terms: 2 and -6, 4r and 3r

2. 5h^2 - 3h^2 - 4h + 3h + 7

   terms: 5h^2, -3h^2, - 4h, 3h, 7       like terms: 5h^2 and -3h^2, - 4h and 3h

3. 6m + 7 - 3m-1

   3m + 6

4. 3(5b +2) - 4

   15b + 6 - 4

Find the area.<br> 7 in.<br> 5 in.<br> 12 in.
vitfil [10]

Answer and Step-by-step explanation:

<u>The area formula for a trapezoid is as follows:</u>

A = \frac{a + b}{2}h

Where:

A = Area

a = top side length

b = bottom side length

h = height

<u>Plug in the values given to you into the equation and solve.</u>

A = \frac{7 +12}{2}(5)

A = \frac{19}{2}(5)

A = \frac{95}{2}

<u>A = 47.5 </u>in.^2<u> is the answer.</u>
