3 2
< 1 and 2 2 are vertical angles
23 and 24 are vertical angles
How do you know that vertical angles are congruent?
m21+ m23 = 180° because the Linear Pair postulate
m22 + m23 = 180° because the Linear Pair postulate
Set the two equations equal to each other since they both equal 180 degrees.
m22+ m23 = m_1 + m23
-m23
-m23
m2 = m_1
Therefore: 22 =21
1. Prove that 23 224 using a similar method.

f(x)=2/3x-8, which give g(x) the greatest value.

step-by-step explanation:

i think it would be c

mark brainliest if im right

step-by-step explanation:

55.44 inches

step-by-step explanation:

part a. assuming a perfectly linear relationship, we can find the slope from the first two data points.

slope = m = (change in rainfall)/(change in years)

= (61.80 -62.33)/(2005 -2004) = -0.53/1 = -0.53

then the point-slope form of the equation of the line can be written as

y = m(x -h) +k . . . . . m = -0.53, (h, k) = (0, 62.33)

y = -0.53x +62.33 . . . x = years after 2004

part b. in 2017, x = 2017 -2004 = 13. then the predicted rainfall is

y = -0.53·13 +62.33 = 55.44 . . inches

the predicted rainfall in 2017 is 55.44 in.

what chart am i supposed to follow?
