There is a straight angle witch mean that both b angles plus 88 equals 180 because a straight angel equals 180. So the solution would be D.
Answer: No 1; x = 44 and
No 2; YA = 8
Step-by-step explanation: In the first parallelogram ABCD, angle D measures x, while angle A measures 3x + 4. Both angles are on the same side of the parallelogram and that means angles A and C are equal while angles B and D are also equal. It also means angles A and D are supplementary (that is, angle A and angle D equals 180). That being the case,
Angle A + Angle D = 180
3x + 4 + x = 180
4x + 4 = 180
Subtract 4 from both sides of the equation
4x = 176
Divide both sides of the equation by 4
x = 44
In the second parallelogram XYZW, diagonal XZ bisects diagonal YW at point A. Where both diagonals bisect each other, is the midpoint for both lines XZ and YW respectively. Hence, line YA equals line WA which can be expressed as
YA = WA
2t = 3t - 4
By collecting like terms we now have
4 = 3t - 2t
4 = t
If t = 4, then 2t (line YA) equals;
YA = 2t
YA = 2(4)
YA = 8
Therefore, (No 1) x = 44,
(No 2) YA = 8
Answer:
a- no they are polling
b-yes there is no point
Step-by-step explanation:
Answer:
8$ a ticket
Step-by-step explanation:
X=adult tickets
Y=student tickets
(9x+13y=212)*4= 36x+52y=848
(4X+15y=168)*9= 36x+135y=1512
subtract both equations -83y=-664
divide by -83 y=8
student tickets cost $8
Answer:
it's D
Step-by-step explanation:
y= .05x+20
x=50
y=.05(50)+20
2.5+20
y=22.5
y=.25x+10
x=50
y=.25(50)+10
12.5+10
y=22.5
