Find the values of x and y.

malfutka [58]

Answer:

y=57, x=77

Step-by-step explanation:

The line that creates x-3 is parrelell to the line that makes 74 degrees

You know that x-3=74

When you simplify you get x=77

Now that you know that x-3=74 you can add all the angles to 180 because they are a supplementary angle

74+41+(y+8)=180, then simplify

115+y+8=180, simplify more

123+y=180

y=57

In quadrilateral QRST, Angle R S T measures (5x+15)°. Angle TQR measures (4x+3)°.

ANTONII [103]

Answer:

RST= 105 degrees

Step-by-step explanation:

it would be 2(5x+15) + 2(4x+3) =360

10x+30+8x+6=360

18x=324

x=18

so RST=5x+15=5(18)+15=105

katen-ka-za [31]

Answer:

The option A and C are correct that is

$-3(x - 8)\\\ \frac{3}{2}(-2x +16)$

Step-by-step explanation:

Given:

$-3x + 24 \\ \textrm {is quivalent to}\\-3(x - 8) = -3x --3\times8 = -3x + 24\\\\\frac{3}{2}(-2x + 16) = \frac{3}{2}\times-2x + \frac{3}{2}\times 16 = -3x + 24$

Therefore, The option A and C are correct that is

$-3(x - 8)\\\ \frac{3}{2}(-2x +16)$
