Well, the best way to solve this is maybe just to find a pattern, so 2, 3, 1, -2, -3, -1, 2, 3, 1, -2, -3, -1, so we find out that it repeats and the sum is 0 every 6 terms! Now that we know this, We can just find out the last two digits, which are 2 and 3. So 2 + 3 =5, which is our answer

Find the value of x. Then find the measure of each labeled angle
Artyom0805 [142]

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°

Step-by-step explanation:

145000 - 129000 = 16000.

16000/145000 = 16/145 = 0.110344828

Therefore there was a 11.0344828% decrease
