In ΔIJK, the measure of ∠K=90°, KJ = 77, IK = 36, and JI = 85. What ratio represents the cosine of ∠I?

We have been given that in ΔIJK, the measure of ∠K=90°, KJ = 77, IK = 36, and JI = 85. We are asked to find the ratio that represents the cosine of angle I.

First of all, we will draw a right triangle as shown in the attachment.

We know that cosine relates adjacent side of right triangle with hypotenuse.

We can see that adjacent side to angle I is IK and hypotenuse is IJ.

Therefore, the ratio of cosine of angle I is .

i believe the answer is 68cm

step-by-step explanation:

i just took 34 x 2 because the space between v and y is the same as y to k.
