The answer is 60.
4x + 12 + x + x =180
solve for x. solve for d. Now you can find angle c.
Answer:
78
Step-by-step explanation:
Solve by PEMDAS.
Parentheses first.
12-5 is 7 and 9x6 is 54, 83-54 is 29.
(7)^2+(29)
Exponent next,
49+29
add them up and you get 78.
Hope this helps! Hit the crown if you want.

Answer:
4.25 0r 5.75
Step-by-step explanation:
First plane
t = 2 hours.
r = r
Second plane
t = 1.5 hours
(30 minutes = 1/2 hour. the second plain has been in the air 2 - 1/2 hour = 1.5 hours. )
r = r + 30
Equation
2 * r + 1.5(r + 50) = 2000
2r + 1.5r + 75 = 2000
3.5r = 2000 - 75
3.5r = 1925
r = 1925 / 3.5
r = 550
the first plane was going 550 mph
the second plan was going 600 mph
If f ( x ) = 5 x - 7
f ( 5 ) = 5 * 5 - 7 = 25 - 7 = 18
- 5 is in the domain
g ( 5 ) = √ ( 5 - 2 ) = √ ( - 3 ) ( this is an irrational number )
- 5 is not in the domain.
