Step-by-step explanation:
<2 + <1 + 20 = 180 A straight line has 180 degrees.
<2 is given as 90 degrees.
90 + <1 + 20 = 180 Combine like terms
<1 + 110 = 180 Subtract 110 from both sides
<1 = 180 - 110
<1 = 70
<1 + <2 + <3 = 180
<1 = 70
<2 = 90
70 + 90 + <3 = 180
160 + <3 = 180 Subtract 160 from both sides
<3 = 180 - 160
<3 = 20
20 + 20 + <4 = 180 Straight line theorem stated above.
40 + <4 = 180 Subtract 40 from both sides
<4 = 180 - 40
<4 = 140
<h3>
Answer:</h3>
10.
<h3>
Step-by-step explanation:</h3>
In order to find the missing value, we need to divide 173.1, by 17.31:
173.1 / 17.31 = 10
Dividing the product (173.1) by one value in the equation (17.31) can represent what the missing value is, in order for 17.31 to equal 173.1
<h3>
Check:</h3><h3>
</h3>
17.31 · 10 = 173.1
173.1 / 10 = 17.31
Answer= B
a=12-x/x and divid all that and you will get the 12 by it self
