Answer:
60 degrees and 30 degrees
Step-by-step explanation:
let the angles be x and y
we are given that the angles are complementary (i.e they sum up to 90 degrees). Hence we can write the first equation:
x + y = 90 ------(eq 1)
we are also given that the difference between the two angles is 30 degrees). Similarly we can write
x - y = 30 ------(eq 2)
now we have a system of 2 equations with 2 unknowns, which we can solve by elimination:
eq 1 + eq 2:
(x + y) + (x - y) = 90 + 30
2x = 120 (divide both sides by 2)
x = 120/2
x = 60 deg (substitute this back into eq 1)
x + y = 90
60 + y = 90 (subtract 60 from both sides)
y = 90 - 60
y = 30 deg.
Answer:
Read a bit so you can understand which one you want.
<u>Percentage</u>
15 skittles, 3 of the 15 are orange.
3 over 15, or 0.2 as a percentage.
So there is a 0.8% chance that he will NOT pick an orange skittle.
<u>Fraction</u>
15 skittles, 3 over 15.
3 over 15 can be 1 over 5.
So there is a 4 over 5 chance that he WONT grab an orange skittle, pretty good odds.
