Answer:
∠ 5 = 151°
Step-by-step explanation:
A linear pair are supplementary, that is sum to 180°
∠ 5 = 5 ∠ 6 + 6 , thus
∠ 5 + ∠ 6 = 180, that is
5 ∠ 6 + 6 + ∠ 6 = 180
6∠ 6 + 6 = 180 ( subtract 6 from both sides )
6 ∠ 6 = 174 ( divide both sides by 6 )
∠ 6 = 29°
Thus
∠ 5 = 180° - 29° = 151°

Answer:
B & D
Step-by-step explanation:
We use percents in decimal form to multiply it with the price. We convert percents into decimals by dividing the percent number by 100. For example, 78% divided by 100 becomes 0.78.
There are two ways to look at it:
- For finding the price we pay during a sale, we focus on the percent we pay. If 22% off is the sale, then we spend 78% or 100-22=78. If 20% off is the sale, then we pay 80% or 0.80. Multiply that by x an unknown price and we have 0.8x.
- We can find the percent off by multiplying the price by the percent conversion. So 20% is 0.20. Then subtract it from the original price to find the leftover that we pay. This is x-0.2x.
