Answer:
p=7
∠BRG=49
Step-by-step explanation:
∠BRG and ∠YRG are on a straight line together. Therefore, they are supplementary and add to 180 degrees.
∠BRG+∠YRG=180
We know that ∠BRG is 7p and ∠YRG is 131 degrees. Substitute 7p in for ∠BRG and 131 for ∠YRG.
7p+131=180
We want to find out what p is. In order to do that, we have to get p by itself. First, subtract 131 from both sides.
7p+131-131=180-131
7p=49
Next, divide both sides by 7.
7p/7=49/7
p=49/7
p=7
Now, we have to find what ∠BRG is.
∠BRG=7p
We know that p=7, so substitute p in for 7
∠BRG=7*7
∠BRG=49
So, p=7 and ∠BRG=49
Answer:
D
Step-by-step explanation:
a² - b² ← is a difference of squares and is factored in general as
(a + b)(a - b)
42² - 38² ← is a difference of squares and factors as
42² - 38² = (42 + 38)(42 - 38) = 80(4) = 320 → D
