Answer:
x=7
Step-by-step explanation:
The two lines indicate that it is an isosceles triangle. This means that the bottom two angles and lengths are the same.
To work this out you would first minus 104 from 180, this gives you 76. Then you would multiply 25 by 2, which gives you 50. This is because the angles are the same. Then you would add 50 to 76, which gives you 126. Then you would multiply 9 by 2, which gives you 18. This is because it is an isosceles triangle and the bottom two sides are the same. Then you would divide 126 by 18, which gives you 7.
1) Minus 104 from 180.

2) Multiply 25 by 2.

3) Add 50 to 76.

4) Multiply 9 by 2.

5) Divide 126 by 18.

6) 
<u>Answer Checking:</u>
<u></u>
To check your answer you would work backwards. First you would multiply 7 by 18, which gives you 126. Then you would minus 50 from 126, which gives you 76. Then you would add 104 to 76, which gives you 180.
1) Multiply 7 by 18.

2) Minus 50 from 126.

3) Add 104 to 76.

<u>Because it is a triangle the internal angles all add up to 180. And so if your answer is 180 then the steps are correct.</u>

Complete question :
Kaitlin has been given a list of 5 bands and asked to place a vote. Her vote must have the names of her favorite and second favorite bands from the list. How many different votes are possible?

Step-by-step explanation:
Total number of bands = 5
To select her favorite ; she chooses 1 from the five ;
Number of bands left = 4
From. The 4 she chooses one ; which is her second favorite
Number of different votes possible :
Favorite selection * second favorite selection
(5 * 4) = 20 different votes.
Answer:
Again every triangle is 180° and so is every straight line, so 180-105 is 75° so 75°+85° is 160 and 180-160 is 20° so your missing angle is 20°
Answer:
a) t=b-5 b) j=b+3+2
Step-by-step explanation:
t is tina, we don't know how much Ben scored so we use b, then subtract 5 because tina got 5 less. same thing for Juan but we add the 3 points he got more than Ben and the 2 extra credit points
