Just do 3x+5+2x=90 And solve for x.
So, 5x+5=90
5x=85
x=85/5 = 17
now you know the value of x, so you can calculate the angles.
Btw the total angle of a triangle is 180, and since this is a right angle triangle, you know that the two angles added together needs to equal 90.
I took this class last year... how could I have forgotten all of this???
K = kims age, s = her sisters age
k = 2s
k + s = 36
2s + s = 36 <== ur equation
3s = 36
s = 36/3
s = 12 <== the sister is 12
k = 2s
k = 2(12)
k = 24 <== Kim is 24
Answer: n=5
Step-by-step explanation: You are solving for ‘n’ so you would want to get ‘n’ by itself on one side of the equation. The easiest way to do this would be to divide both sides by 3, which would make ‘3n’ turn to ‘n’ and 15 into 5.
