Let
x = measure of angle TAP
y = measure of angle BRE
We're told that "angle BRE is its own complement" meaning that angle BRE added to itself is 90 degrees. In algebraic terms, we can say
y+y = 90
2y = 90
2y/2 = 90/2
y = 45
So angle BRE is 45 degrees. Note how 45+45 = 90.
We also know that angle TAP and angle BRE are supplementary. They add up to 180 degrees
x+y = 180
x+45 = 180 ... replace y with 45
x+45-45 = 180-45 ... subtract 45 from both sides
x = 135
Since we defined x to be the measure of angle TAP, this means that angle TAP is 135 degrees
Answer: The answer is 80 mph.
Step-by-step explanation: 1. Divide 14 from 571.
2. You'll get the answer 40. So it's 40 mph.
3. If she's trying to shorten by 1/2 then she should drive 80 mph because if you drive 80 mph it will take 7 hours instead of 14 hours. (She'll go 7 hours because you divide 14 hours by 2. Then you have to multiply 2 to 40.)
Answer:
2,3
Step-by-step explanation:
3w-7w-12=2w-6
-4w-12=2w-6
-12=6w-6
-6=6w
w=-1
I would would say 7.
Mom + Dad + daughter + daughter + daughter + daughter + plus one brother = 7
Since they are all sisters and it says each one has one brother I think that would mean 7. That's just my comprehension of the question, though I may 100% wrong.
