Answer:
PLEASE GIVE BRAINLIEST IT IS 118
Step-by-step explanation:
(18x+28)+(7x+27) equals 180 degrees
25x+55= 180
25x=125
x=5
THIS MEANS THAT ANGLE ABC IS
18(5)+28.
90+28.
118 degrees. And since angle abc is equal to efg that is your answer.
X=8.33
u have to isolate the x on a side ans the numbers on the other side of the equation
Answer: The answer would be
D - 12.25x + 3.99 = 77.49
Step-by-step explanation:
If each shirt costs $12.25, that would be 12.25 times “x” amount of shirts. Then, you add the $3.99 shipping amount. Which all equals 77.49.
2x -20 -1 =0
2x -21=0
2x=21
x= 10.5
Answer: y = 0.5, x = 50
Step-by-step explanation: Both triangles in the picture are isosceles, telling us that the 2 angles at the bottom are congruent. With this, we can find y by doing the following:
a triangle has 180 degrees so we subtract the given 50 which gives us 130
2(2y + 64) = 130
4y + 128 = 130
y = .5
This means that the bottom 2 angles are both 65. Since the top angle of the second triangle is supplementary to the bottom angle of the first one, the top angle of the second triangle is 115. So, we find x by:
2(45 - x/4) = 65
x = 50
This means the bottom 2 angles of the second triangle are both 32.5.
