Please please help me ! I’m on my final part of the test and I need to finish this question ! I will mark you as brainliest!! Given measure of angle ^ADC = 165° and measure of angle ADB = 14x+5
1. Write a simplified expression for the measure of angle ^CDB.
2. Explain your reasoning in writing the expression for
the measure of angle ^CDB.

90°

i went on a whim and guessed it was a right angle, sorry I can't provide reasoning! but it is for sure 90°

Step-by-step explanation:

14x + 5 + 90 = 165

14x + 95 = 165

       -95    -95

14x = 70

/14    /14

x = 5

14(5) + 5 +90 = 165

70 + 95 = 165

165 = 165

the line of

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
