The answer is 30,60,90. Because 60 is twice the number 30 and 90 is three times the first number.
Step-by-step explanation:
Question 10 :
3x + 6 = 4x – 12 ( reason: corresponding angles due to parallel lines)
simplify and get x, thus x = 18
to find 3x + 6 or 4x - 12(which is both the same),
3(18) + 6 = 60° , 4(18) - 12 = 60°
Question 11:
2x + 24 + x = 180 ( reason: interior angles due to parallel lines)
simplify again to get x, you will get x = 52
then find the individual by subbing in the value of x into the equation.
so 2x + 24 = 2(52)+24 = 128° and x = 52°
Answer:
The last one.
Step-by-step explanation: Because 1/2 divided by 4 = 1/8 and 1/2 x 4/1 = 2
10 because x+x = 20
