The angles of a triangle all add up to 180º.
You need to set up and solve the equation:
84+48+3h = 180
Answer: 1.) 14.66666666666667
2.) 20
Steps:
1.) 180 = 3x + 136
180 -136 = 3x
44 = 3x
44/3 = x
14.66666666666667 = x
2.) 70 + x = 90
x = 90 - 70
x = 20
I would appreciate brainliest if this was helpful and correct! ;)

Answer:
$22.40
Step-by-step explanation:
Set up the equation like this: 2.5x + 4 = 60
Then solve for x.
For the table 0.2 would be (1/5) 0.5 would be (1/2). And 0.7 would be (7/10).
For number 2 I would say the denominator changed each time
