Find the measure of the missing angle

a=

Hello! a = 107

Step-by-step explanation:

This is a supplementary angle meaning it will add up to 180 degrees so...

180 - 73 = 107 therefore a = 107 hope that helps!

107

Step-by-step explanation:

The two angles form a straight line so they add to 180 degrees

73+a = 180

Subtract 73 from each side

a = 180-73

a = 107

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23
