We know complementary angles make a sum of 90°. We have angles “x” and “x+30”, so we know that
x+x+30=90
So:
2x=90-30
2x=60
x=60/2=30°
So our angles would be:
Angle x=30°
Angle x+30=60°
412+812=1,224 because 2 +2 = 4, 1+1=2 so, so fair we have 24, 8+4=12, Connect it together then u get 1,224 .
Answer:
ΔABC tan C=AB/BC
⇒ tan 55.8= 8.96/BC ⇒BC= 8.96/tan 55.8
BC=x= 6.09

f^-1(x) = sq.rt 5(x - 10)/5, sq.rt 5(x - 10)/5 is the inverse of y = 5x^2 +10
Step-by-step explanation:
interchanging the variables
x = 5y^2 + 10
5y^2 +10 = x
5y^2 = x - 10
dividing by 5
5y^2/5 = x/5 + -10/5
y^2 = x/5 + - 10/5
y^2 = x/5 - 2
y = 5 (x-10) 0/5 (sq.rt)
g(5x^2 + 10) = 5x/5
g(5x^2 + 10) = x
f^-1(x) = sq.rt 5(x - 10)/5, sq.rt 5(x - 10)/5 is the inverse of y = 5x^2 +10
