For the figure shown on the right, find the value of the variable and the measures of the angles. X=__

Q= 114°

R= 37°

P= 29°

x= 37

Step-by-step explanation:

x + x-8 + 3x +3 = 180

5x -5 = 180

5x = 175

x= 37

R = x = 37°

p= x-8 = 37-8 = 29°

Q = 3x+3= 3×37+3 = 114°

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

( - 4 , -7 )

all the lines must parallel  

step-by-step explanation:

coordinates of c = ( - 1 , 2 )

3 units left = ( -4 , 2 )

9 units down = ( - 4 , 11 )
