Step-by-step explanation:

use CAH method (Cos angle = adjacent/hypotenuse)

Given adjacent = 5

Hypotenuse = 12,

$\cos(x) = \frac{adjacent}{hypotenuse} \\ \cos(x) = \frac{5}{12} \\ x = {cos}^{ - 1} ( \frac{5}{12} ) \\ = 65.4deg(nearest \: tenth)$

In the diagram shown, C is the midpoint of BD. What is the

taurus [48]

Answer:

AC = 20

Step-by-step explanation:

C is the midpoint of BD.

That means that BC = CD

BC = x + 4

CD = 3x - 10

x + 4 = 3x - 10 Subtract x from both sides

4 = 3x - x - 10 Combine

4 = 2x - 10 Add 10 to both sides

4 + 10 = 2x - 10 + 10 Combine

14 = 2x Divide by 2

14/2 = 2x/2 Combine

7 = x

AC = AB + BC

AC = 2x - 5 + x + 4

AC = 3x - 1

AC = 3*7 - 1

AC = 21 - 1

AC = 20

A costume designer needs to make 12 costumes for the school play. Each costume requires 2 2/3 yards of fabric. How many yards of

Alexus [3.1K]

Answer:

Length of fabric the designer needs to make 12 costumes = 32 yards

Step-by-step explanation:

Length of fabric required for each costume = $2\frac{2}{3}\ yards$

Total number of costumes to be made =12

Total length of fabric required for all the costumes = $12\times 2\frac{2}{3}$

We can multiply mixed numbers by converting it to fractions.

$12\times 2\frac{2}{3}$

⇒ $12\times \frac{8}{3}$

⇒32 yards

Length of fabric the designer needs to make 12 costumes = 32 yards
