(2x-4) / 5 = x + 4. Mult. both sides by 5 to eliminate the fraction on the left side:
2x-4=5x + 20
Combining like terms, 3x = -24, and so x = -8
Answer: m=45° n=15°
Step-by-step explanation:
ok so idk if you know about the 45-45-90
the first triangle has a 45° angle and 90° angle.
these equal to 135°, 180- 135 is 45.
so m= 45°.
the other triangle looks like it could be equilateral.
so that's 60-60-60.
since m= 45°
60-45= 15
therefore n= 15°
