Find the missing side. round to the nearest tenth.
horrorfan [7]

Answer:

24) x = 9.2

25) x = 30.8

Step-by-step explanation:

Given

See attachment for triangles

Solving (24)

To solve for x, we make use of cosine formula

i.e.

cos(40) = adjacent ÷ hypotenuse

So, we have:

cos(40) = x ÷ 12

Multiply both sides by 12

12 cos(40) = x

12 * 0.7660 = x

x = 9.2

Solving (25)

To solve for x, we make use of sine formula

i.e.

sin(25) = opposite ÷ hypotenuse

So, we have:

sin(25) = 13 ÷ x

Multiply both sides by

x sin(25) = 13

Divide by sin(25)

x = 13 ÷ sin(25)

Using a calculator

x = 30.8

How do you solve #23?
scZoUnD [109]

Answer:

m= 67.5 and n=56.25

Step-by-step explanation:

  180-15=165

  165/2= 82.5

  90-15= 75

  75+75= 150

  180-150=30

  30+82.5= 112.5

  180- 112.5= 67.5

  m= 67.5

  180-67.5= 112.5

  112.5/2= 56.25

  n= 56.25
