Answer: GEF = 30 DEF = 40
Step-by-step explanation: By angle summation we know the entire angle
GED = 70, so the smaller angles that make up GED (GEF and DEF) will have to sum up to equal GED. Using this we get:
2x + 10 + 5x - 10 = 70
From here we can combine like terms:
7x = 70
and solve for x
x = 10
Then we can plug the value of x back into the equations given to solve for GEF and DEF
GEF:
2x+10 == 2(10)+10 = 30
DEF:
5x-10 == 5(10)-10 = 40
Answer:
x = -16
Step-by-step explanation:
52= 1/2x+15−3.25x−7
Combine 1/2x and −3.25x to get −11/4 x.
52= −11/4x+15−7
Subtract 7 from 15 to get 8.
52=−11/4x+8
Swap sides so that all variable terms are on the left hand side.− 11/4x+8=52
Subtract 8 from both sides.
− 11/4x=52−8
Subtract 8 from 52 to get 44.
−11/4 x=44
Multiply both sides by − 4/11
the reciprocal of − 11/4
x=44(−4/11)
Express 44(−4/11 ) as a single fraction.
x= 44(−4)
Multiply 44 and −4 to get −176.
x= −176/11
Divide −176 by 11 to get −16.
Since X increases by 1,
Divide the 2nd Y value by the first Y value:
4/6 = 2/3
The answer is 2/3
