Answer:
x = 168.75°
Step-by-step explanation:
<u>Angle Measurement Units</u>
To convert from different units for angle measurements, we have to recall that:
180 degrees = π radians
If we are given the angle in degrees, multiply by π/180 to convert it to radians.
If the angle is given in radians, multiply by 180/π to convert to degrees.
We are given the angle:
Multiplying by 180/π:
Simplifying:
x = 168.75°
Answer:
132 cm^2
Step-by-step explanation:
7x4 is 28 for the top rectangle.
Bottom left triangle is bh/2 which here is 8x6/2 which is 24.
The same goes for the bottom right triangle.
Lastly the middle triangle is 7*8 which is 56.
Hence, 56+28+24+24=132!
Hope it helped!

Answer: x=3 y=3
Step-by-step explanation:
Assuming you meant 2x+3y=15 as the first problem. You have to make either both the x’s or both the y’all equal in both equations first. Multiply the second equation by 2 (for x’s) and you’ll get 2x+2y=12. The 2x cancels out so you’re left with 3y=15 and 2y=12. Subtract 2y=12 from 3y=15 and you get y=3.
Repeat to figure out x. Multiple second equation by 3 (for equal y’s) and you get 3x+3y=18. This time the first equation is being subtracted from the second one. (3x+3y=18) - (2x+3y=15). Y’s cancel out and you’re left with (3x=18)-(2x=15. Subtract and you get x=3
