Step-by-step explanation:
8x-10=3x+90
=5x=100
=x=20
therefore
B=3(20)+90
150°
8/x= 2/5
8•5= 2•x
40=2x
40/2= x
20= x
Step-by-step explanation:
the answer is in the above image
i think the answer is 60xT
or 120 liters per minutes
Answer:
4/5
Step-by-step explanation:
In a right triangle such as this one
cos (angle) = adjacent leg / hypotenuse
cos(k) = KL / 15
You will need to find the leg length KL using Pythagorean Theorem
15^2 = 9^2 + (KL)^2 KL = 12
then cos k = 12/15 = 4/5
