D) Picking up 12 kids for a party and then dropping 12 kids off at the pool
Answer:
D. sin m∠C = 2 square root of 5 all over 5
Step-by-step explanation:
The triangle ABC is a right angled triangle. The angle ∠C is where we are asked to find. The side AB measures 6 , AC measures 3 and the side BC measures 3√5.
The longest side of a right angle triangle is the hypotenuse, that means the side with length 3√5 is the hypotenuse.
Therefore side BC is the hypotenuse side and we are asked to find the angle C. AB is the opposite side while AC is the adjacent side.
Using
sin C = opposite/hypotenuse = 6/3√5 = 2/√5 = 2√5/5
cos C = adjacent/hypotenuse = 3/3√5 = 1/√5
The equation is: 5x - x = 1044
Now, What you have to do here is simple.
First, subtract x from 5x and you get 4x.
4x =1044
Here you divide both sides by 4. 4x becomes x and 1044 becomes 261.
x = 261
We have the first number. To get the other one we have to multiply 261 by 5.
261 * 5 = 1305
the answer is 1305
So:
x= 261
5x=1305
Hope you understand.
Answer:
5y = -1x
Step-by-step explanation:
Those 2 expressions are equivalent, so they don't tell us anything. This means that the answer in simplest is the starting expression - 5y = -1x
