Answer:
angle 1+angle 2 = 180 degrees
Step-by-step explanation:
when 2 angles are supplementary, they equal 180 degrees when they are added up. Because angles 1 and 2 are supplementary, this means that angle 1 + angle 2 equals 180 degrees.
Answer:
y = -3x-2
Step-by-step explanation:
the slope can be found using rise/run which comes out to be -3/1 and you can drop the 1 from the fraction to have -3. and then the y-intercept is found from where the line crosses the y-axis
A=pir^2
C=2pir
=>r=C/2pi
g(c)=pi(C/pi)^2
