Question 7

Question 7 - Solve for x.
You can take the numbers out of the ( ) before you add them together.

Question 9

Question 9 - Optional
Bonus! Solve for x.

x = 36 degrees

Question 1

Question 1: Solve for x.
These angles are COMPLEMENTARY. They add up to 90 degrees. This means x + 18 + x = 90.
Don't forgot to "Combine Like Terms" (like this: 2x + 18 = 90), then solve!

x = 24 degrees

x = 36 degrees

x = 81 degrees

Question 2

Question 2: Solve for x.

x = 35 degrees

x = 48 degrees

x = 68 degrees

x = 71 degrees

Question 3

Question 3: Solve for x.

x = 35 degrees

x = 42 degrees

x = 80 degrees

Question 4

Question 4 - Solve for x.

Question 5

Question 5 - Solve for x.
These angles are SUPPLEMENTARY. They add up to 180 degrees. This means x + 20 + x + 10 = 180.
Don't forgot to "Combine Like Terms" (like this: 2x + 30 = 180), then solve!

x = 40 degrees

x = 65 degrees

x = 75 degrees

Question 6

Question 6 - Solve for x.
You can take them out of the ( ) before you add them together.
Like this: x + x - 50 = 180.
Don't forget to Combine Like Terms before you solve!

x = 60 degrees

x = 85 degrees

x = 100 degrees

Question 7

Question 7 - Solve for x.
