Can someone me with the question in the image

x = 45°

Step-by-step explanation:

the sum of the interior angles of a figure = (number of sides - 2) * 180

the sum of the interior angles of this figure = (5 - 2) * 180 = 540°

to find the value of x:

90 + 148+ 2x + 10 + 2x + 112 = 540

2x + 2x = 540 - 90 - 148 - 10 - 112

4x = 180

x = 180/4

x = 45

i can't solve unless i know what the line is

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
