A triangle has two side lengths, 4cm and 9cm. Which of the following could be the length of the third side

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.

do you mean add both of the equations together

because if you do the answer is 10x-5

step-by-step explanation:

25.2

step-by-step explanation:

2+4x6-8/10= 25.2

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
