The answer is 4. 7+(-3) is like 7 minus 3.
So those to angles added together equals 180° thus all you have to add those together and set it equal to 180 to find hat x equals, and then add 89 to it to find the highlighted angle.
x+109+x+89=180
add the numbers and x's together
2x+198=180
subtract 198 from each side
2x = -18
divide each side by 2
x = -9
Put -9 in for x in the equation x+89 to find that angle
-9+89
=80
ANSWER:
That angle equals 80°
One approach that might be a great help would be if you would look
at the choices ... those things at the bottom of the question that you
didn't give us.
-- One leg is 3 times the length of the other leg.
-- Any right triangle that has one leg three times as long as the other
leg is similar to this triangle.
I'll bet that if you look through the choices, you'll find one there.
Answer:
Q1: 48
Q2: 59
Step-by-step explanation:
Tim spends 1/3 each weekday sleeping and 7/24 in school. We can write 1/3 as 8/24 so we have a common denominator. Now we can see that Tim sleeps for 1/24 time of a weekday more then he spends in school.
I hope that's what you meant.
