Answer:
Step-by-step explanation:
Given the quadratic inequality we are to find the interval of x
x² − 8x + 15 < 0
Factorize
x²-3x-5x+15<0
x(x-3)-5(x-3)<0
(x-3)(x-5)<0
(x-3)<0 and x-5<0
if x+3<0
x<-3
If x-5<0
x<5
Hence the solution yo the quadratic inequality are x<3 and x<5
Hence
Sometimes you just need to take a moment and really look for some hints that’ll help you. Rotate your page, maybe colour some lines.
Take a look at the picture, I coloured the lines and saw that the red and green angles are actually the same. And since the 90° angle is given, just subtract it from 140° to get your answer.
x = 50°
Multiply 3/5*35. Numerator * numerator, denominator*denominator. Simplify before multiply.
