In ΔIJK, the measure of ∠K=90°, KJ = 65, IK = 72, and JI = 97. What is the value of the cosine of ∠J to the nearest hundredth?

kow [346]

Answer:

$\cos(J) = 0.67$

Step-by-step explanation:

Given

$\angle K = 90^o$

$KJ = 65$

$IK = 72$

$JI = 97$

Required

$\cos(J)$

The question is illustrated with the attached image.

From the image, we have:

$\cos(J) = \frac{KJ}{JI}$

This gives:

$\cos(J) = \frac{65}{97}$

$\cos(J) = 0.67010309278$

$\cos(J) = 0.67$ --- approximated

Equation with angle addition can someone please answer please help

nalin [4]

PQ peependicular to PS

Thus angle QPS = 90⁰

$\angle QPR + \angle RPS = \angle QPS$

7x - 9 + 4x + 22 = 90⁰

11x = 77

x = 7

Thus angle QPR = 7(7) - 9 = 40⁰
