Answer:

12

Step-by-step explanation:

x - 3\frac{1}{2} = 8.5          

x - \frac{7}{2} = 8.5         Convert the mixed fraction to a imroper fraction.

x - 3.5 = 8.5     Convert the improper fraction to a decimal number.

x = 12                Add 3.5 to both sides.

in a right triangle, the leg opposite to the angle of 30 degrees is 7 in. find the lengths of the hypentenuse and the other leg
satela [25.4K]
Answer:

Hypotenuse = 14 inches

Adjacent = 12.12 inches

Step-by-step explanation:

Using SOH, CAH TOA Method

According to SOH

Sin(theta) = Opposite/Hypotenuse
Given theta = 30°
Opposite = 7 inches

Sin30° = 7/Hypotenuse
Hypotenuse = 7/Sin30°
Hypotenuse = 7/0.5
Hypotenuse = 14 inches

The other leg will be the adjacent saying x using Pythagoras Theorem to get x
Hypotenuse^2 = Opposite^2 + Adjacent^2
14^2 = 7^2 + x^2
x^2 = 14^2 - 7^2
x^2 = 196 - 49
x^2 = 147
x = sqrt of 147
x = 12.12 inches

SIMILAR TRIANGLES<br> Solve for x.
patriot [66]

Answer:

<h2>x = 9 1/3</h2>

Step-by-step explanation:

To do this, we need to do a few things. I'll put the steps separate so you can easily understand.

<h3>Step 1: Set up a proportion</h3>

\frac{14}{6} = \frac{x}{4}

<h3>Step 2: Cross multiply</h3>

6x = 14 x 4

6x = 56

6x = 9 1/3

<h3>Step 3: Check</h3>

\frac{14}{6} = \frac{6}{9\frac{1}{3} }

Cross multiply to check if they equal

6 x 9 1/3 = 14 x 4

56 = 56 ✔

<h3>Step 4: Answer</h3>

x = 9 1/3

I'm always happy to help :)
