If two angles form a linear pair and the measure of one of the angles is 73º, what is the
measure of the other angle?

107°

Step-by-step explanation:

Linear pairs are supplementary so they have to add up to 180°.

x = meas. of other angle

x + 73 = 180

Subtract both sides by 73

x = 107

The measure of the other angle is 107°.

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
