Answer:
15
Step-by-step explanation:
multiply both sides by 15
45x=675
Divide both sides by 45
x=15
Answer:
x = 8
Step-by-step explanation:
Since the sum of all angles of a parallelogram is equal to 360 degrees, <Z + <Y is half of the parallelogram, and therefore <Z + <Y = 180 degrees.
16x-4 + 7x = 180, combine like terms
23x - 4 = 180, add 4 on both sides (isolate variable)
23x = 184, divide 23 on both sides
x = 8
Answer:
∠RST = 40°
Explanation:
We are given that:
SQ bisects angle RST.
This means that:
∠QST = ∠QSR
2x = 3x - 10
10 = 3x - 2x
x = 10
Therefore:
∠QST = 2x = 2(10) = 20°
∠QSR = 3x - 10 = 3(10) - 10 = 30 - 10 = 20°
Note that both angles are equal.
Now, we can get ∠RST as follows:
∠RST = ∠QST + ∠QSR
∠RST = 20 + 20 = 40°
Hope this helps :)
First you have to distribute. -3y +12=18. -3y=6. y= -2.
Answer:
A1=59
A2=85
A3=49
A4=no.because strait lines add up to 180 and it does not
B1=x=133andy=133
B2=53,61,and 56
B3=x=37andy= 37
B4=x=54and y=68
C1=y= 43and x=51
