X: 90 degrees. y: 43 degrees
We know that x is a right angle. The way we find y is to add 47 + 90 which gives us 137. We also know that a right triangle adds up to 180. So, we subtract 137 from 180. This means that y would be 43 degrees.
2.47*10^8=247000000
take 2.47 and move the decimal point 8 times to the right. Fill empty spaces with zeros
Answer:
-3'1
-6'1
Step-by-step explanation:
the bottom left and top right are always going to be negative. The right top and bottom are positive numbers. so the answer is -3'1 for the first top one then the second bottom dot is -6'1
Answer:
n = -3 or 8
Step-by-step explanation:
2n² = 10n +48 (rearrange)
2n²- 10n - 48 = 0 (divide all terms by 2)
n²- 5n - 24 = 0
by factorization,
(n+3)(n-8) = 0
hence,
n+3 = 0 ----> n = -3
or
n-8 = 0 ----> n = 8
