Answer:

d.) $\frac{24}{7}$

Step-by-step explanation:

using the sohcahtoa method, where tan A = $\frac{opposite}{adjacent}$ , our opposite side is 24, and our adjacent side is 7. our hypotenuse, the longest side, is 25. therefore, we get: d.) 24/7

Trigonometry

Alchen [17]

The area of the triangle PQR is 17.6 square units.

Explanation:

Given that the sides of the triangle are PQ = 12 and PR = 3 and $m\angle P = 78^{\circ}$

We need to determine the area of the triangle PQR

<u>Area of the triangle:</u>

The area of the triangle can be determined using the formula,

$\text {Area}=\frac{1}{2} qr \sin P$

Substituting the values, we get,

$\text {Area}=\frac{1}{2}(12)(3) \sin 78$

Simplifying, we have,

$\text {Area}=\frac{1}{2}(36)(0.98)$

Multiplying the terms, we have,

$\text {Area}=\frac{35.28}{2}$

Dividing, we get,

$\text {Area}=17.64$

Rounding off to the nearest tenth, we have,

$Area=17.6$

Thus, the area of the triangle PQR is 17.6 square units.

Find the quotient. Write your answer in simplest form.<br><br> 1/3 ÷ 6= 1/18?

Anna007 [38]

If you would like to solve 1/3 / 6, you can do this using the following steps:

1/3 / 6 = 1/3 / 6/1 = 1/3 * 1/6 = 1/18

The correct result would be 1/18.

If f(x)=-4x+1 what is f(-x/2)

guapka [62]

Answer:

f( $\frac{-x}{2}$ )=2x+1

Step-by-step explanation:

given f(x)=-4x+1................(1)

x= $\frac{-x}{2}$ put in equ (1)

f(x)=-4x+1

f( $\frac{-x}{2}$ ) =-4( $\frac{-x}{2}$ )+1

f( $\frac{-x}{2}$ )=2x+1 answer

A triangle has three different integer side lengths and a perimeter of 20 units. What is the max length of any one side?

Troyanec [42]

X + x+1 + x + 2 = 20
3x + 3 = 20
3x = 17 but can't start with x = 6 because 6+7+8 > 20,
so have start with 5 + 6 + 7 = 18 are the 3 sides.
