Let's first calculate the length of the diagonal of the base. Using the Pythagorean theorem:
b = sqrt(9^2 + 7^2) = sqrt(81 + 49) = sqrt(130) = 11.40175425
Now the length of the diagonal to the box. Once again, using the Pythagorean theorem:
d = sqrt(15^2 + 11.40175425^2) = sqrt(225 + 130) = sqrt(335) = 18.84144368
We now have a right triangle where we know the lengths of all three sides. The lengths are:
a = 15
b = sqrt(130) ≠11.40175425
c = sqrt(335) ≠18.84144368
we want the angle opposite to side a. So
tan(A) = 15/11.40175425 = 1.315587029
A = atan(1.315587029)
A = 0.92085175 radians
Answer:
Step-by-step explanation:
acute ks little angles
obtuse is big angles
in a riangle it adds up to 180
I think it is B. and the amount that they each need to pay is $1.13
A. 400, 500
The question mentions you make a profit, which is to make more money than what you spent or put in. All other choices would make the statement say you ended up having less money, which is money lost, not profit.
Answer:
6x+48+15+3x and 9x+63
Step-by-step explanation:
3(2x+16)=6x+48 and 3(5+x)=15+3x. 6x+48+15+3x=9x+63 .
