Answer:
4/3
Step-by-step explanation:
Answer:
Answer is m∠4=40
Step-by-step explanation:
take note that m∠6 & m∠7 are vertical angles. Vertical angles are equal to each other, therefore m∠6 is equal to m∠7.
m∠6 = m∠7 (vertical angles)
11x + 8 = 12x – 4
12x - 11x = 8 + 4
x = 12
so
m∠6 = 11x + 8
m∠6 = 11(12) + 8
m∠6 = 132 + 8
m∠6 = 140
m∠4 = 180 - m<6
m∠4 = 180 - 140
m∠4 = 40
The rise & run for ΔABC is 1 and 3.
The slope is 1/3 because it is rise over run.
For ΔDFA, the rise and run is 2 and 6.
2/6 is equal to 1/3, so the slope is constant.
Hope this helps!
