Answer:

Step-by-step explanation:

use substitution and solve this 8x+4(-2x+3)=12

with the 4 distributed its

8x-8x+12=12

then you can cancel out the 8x and -8x and switch the 12 over into a -12 canceling out the 12s making it x=0

PLEASE HELP ME!<br> I have to find the measurement of the angle but i can't figure it out.
Vadim26 [7]

<u>Answer:</u>

  • The value of ∠TMV is 45°.

<u>Step-by-step explanation:</u>

<u>We know that:</u>

  • ∠VTM + ∠TMV + ∠MVT = 180°
  • ∠VTM = 92
  • ∠MVT = 43

<u>Work:</u>

  • ∠VTM + ∠TMV + ∠MVT = 180°
  • => 92 + 43 + ∠TMV = 180°
  • => 135 + ∠TMV = 180°
  • => ∠TMV = 180 - 135
  • => ∠TMV = 45°

Hence, <u>the value of ∠TMV is 45°.</u>

Hoped this helped.
