Solve for x. Leave your answer in the simplest radical form.

Gala2k [10]

Answer:

x = sqroot(122)

Step-by-step explanation:

First find the line that goes thru the middle of the shape. It is the hypotenuse of the bottom/left triangle. Use the pythagorean thm.

9^2 + 5^2 = h^2

81 + 25 = h^2

sqroot106 = h

Now sqroot106 is a leg in the right triangle that is on the top/right in the image.

Use pythagorean thm again.

4^2 + (sqroot106)^2

= x^2

16 + 106 = x^2

122 = x^2

sqroot122 = x

Precal : Note: Triangle may not be drawn to scale. Suppose a = 3 and A = 15 degrees

drek231 [11]

Given:

In a right triangle at B,

$\begin{gathered} a=3 \\ A=15^{\circ} \end{gathered}$

To find:

The length of the sides b and c and angle B.

Explanation:

Using the trigonometric ratio,

$\begin{gathered} sinA=\frac{a}{c} \\ \sin15^{\circ}=\frac{3}{c} \\ c=\frac{3}{\sin15^{\circ}} \\ c=11.59 \\ c\approx11.6 \end{gathered}$

Using the trigonometric ratio,

$\begin{gathered} \tan A=\frac{a}{b} \\ \tan15^{\circ}=\frac{3}{b} \\ b=\frac{3}{\tan15^{\circ}} \\ b=11.19 \\ b\approx11.2 \end{gathered}$

Using the angle sum property,

The angle B becomes,

$\begin{gathered} 90+15+B=180 \\ B=180-90-15 \\ B=75^{\circ} \end{gathered}$

Final answer:

The values are,

$\begin{gathered} b=11.2 \\ c=11.6 \\ B=75^{\circ} \end{gathered}$

Please help ASAP!!!!!

Answer: first answer choice (1/3) (p+45)

Step-by-step explanation:

to do this, factor out 1/3 from each element

so divide 1/3 p by 1/3 and 15 by 1/3

(1/3 p) / (1/3 ) = p

15 / (1/3) = 15 * 3 = 45

now put 1/3 outside of the parentheses

(1/3) (p+45)
