Answer:

b = 3

Step-by-step explanation:

3(9+9b)=69+136

27+27b = 205

27b = 205-27

27b = 178

b = 178/27

*slaps face*

In the comments you said the "136" is "13b" so ok...

3(9+9b)=69+13b

27+27b = 69 + 13b

27+14b = 69

14b = 69-27

14b = 42

b = 3

Help please I needed! Find the missing sides please attach your work!
evablogger [386]

Answer:

x = 32

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

sin theta = opp side / hypotenuse

sin 30 = 16/ x

Multiply each side by x

x sin 30 = 16/x * x

x sin 30 = 16

Divide each side by sin 30

x = 16/ sin 30

x = 16 / (1/2)

x = 32
