Answer:
2
Step-by-step explanation:
these are alternative interior angles so they are equal to each other (congruent) soooo
9x + 4 = 3x + 16
subtract:
9x = 3x + 12
6x = 12
divide
x = 2
4.the dot would be on 1 1/2 and the x would be pointing toward the negative numbers
For number 9. its 34 × 65 = 65 × 34.. So that means its communicative property
Answer:
1. 90-68= 22
2. 90-80= 10
3. 90-3= 87
Step-by-step explanation:
A complement angle is found by their sum being 90 degrees. So, you are looking for the angle that would add to the given angle to = 90.
