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
the answer to the questions "the quotient of 6 and n" is 6n
Answer:
B = 80
Step-by-step explanation:
y = 4x
y = 1/2x + 280
Substitute one equation into another.
4x = 1/2x + 280
Combine like terms
3.5x = 280
x = 80
Answer:
the difference between the highest and lowest values in a set of numbers.
Step-by-step explanation:
Volume = l x w x h
Volume = 1x1x1/4
Volume = 1/4 cm^3
