Since they are complementary
x + y = 90
Sin(o) = Cos (90-0)
Therefore, Cos x = Sin y = 4/5 [ Because x and y are complementary]
Answer:
27 degrees and 63 degrees
Step-by-step explanation:
Let n be the number.
Angle 1: 2n-15
Angle 2: 3n
If the angles are complementary they add up to 90.
Therefore we can write an equation.
2n-15+3n=90
Combine like terms
5n-15=90
Add 15 to both sides
5n=105
n=21
Now we plug 21 in for n and solve for the angles
Angle 1 = 2(21)-15
Angle 1 = 42-15
Angle 1 = 27
Angle 2 = 3(21)
Angle 2 = 63
In the question there are numerous information's of immense importance already given. Let us write them down first
Distance traveled by bike = x km
Distance traveled by bus = y km
Total distance traveled by George and Carmen = 325 km
Then
x + y = 325
Another equation can be determined by
x - y = 75
x = y + 75
Now we will put the value of x in relation to y in the first equation.
x + y =325
y + 75 + y = 325
2y = 325 - 75
2y =250
y = 250/2
= 125 km
Now putting the value of y in equation given below, we get
x + y = 325
x + 125 = 325
x = 325 - 125
= 200 km
So the distance they biked is 200 km and the distance they traveled by bus is 125 km.

Answer:
B. 4 and 6/10
Step-by-step explanation:
in order to find this answer i've always had a trick where i first off find an even number to divide these with and in this case that would be 4 and then the leftovers would be 6/10 and in this case your answer would be right there 4 and 6/10 but if needed to be simplified it would be 4 and 3/5
hope this helps, if it did please make sure to like and rate and give me the brainliest if possible!
have a good day!
