Answer:
7x+21y=5439
x+y=305
Step-by-step explanation:
it's pretty self explanatory, right?
2x^2=(3root2)^2
2x^2=9(2)
x^2=9
x= 3,-3
x=3 because your side length can’t be negative.
Volume of the pentagonal prism =
Area of the pentagon• height of the prism
Answers:
B = 50
a = 10.9
c = 17.0
================================================
Explanation:
This is a right triangle, so the acute angles are complementary, meaning they add to 90
B+40 = 90
B+40-40 = 90-40
B = 50
Also, because this is a right triangle, we can use trig ratios to compute the missing sides
tan(angle) = opposite/adjacent
tan(40) = a/13
a = 13*tan(40)
a = 10.908
a = 10.9
cos(angle) = adjacent/hypotenuse
cos(40) = 13/c
c*cos(40) = 13
c = 13/cos(40)
c = 17.0
note: make sure your calculator is in degree mode
(-1,1)
This is because the solution is the point where the two lines meet.
