Which equation can be used to find the measure of angle lkj? cos−1 = x cos−1 = x sin−1 = x sin−1 = x

D

Step-by-step explanation:

We are given that a triangle LKJ

LJ=8.9 cm

KJ=10.9 cm

We have to find the measure of angle LKJ

To find the value of angle LKJ we will use Sin x

Substitute the values then we get

Hence,option D is true.

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36
