Answer:
60
Step-by-step explanation:
180-120=60so the answer is a 60
Answer:A = 7 - 124/X
Step-by-step explanation:
Answer:
15% of 100,000 is 15000, so that would be 100,000 + (15,000*3) = 145,000 after 3 years.
Angle a and b are supplementary angles which means that when added they equal 180.
so we must set our equation equal to 180.
8x+74+2x+56=180
which simplifies to 10x+130=180
then subtract 130 from both sides.
10x=50
x=5
So we plug in 5 to find the measure of b.
2(5)+56=b
10+56=b
66=b
the measure of angle b is 66 degrees
