Since sides kl and kj are congruent that means that angles klj and kjl are congruent. if angle klj is 58 then that means kjl is also 58. so you take the total number of degrees in a triangle (180) and subtract 58 and 58 (116) which leaves you with 64 ( the degree measure of lkj)

Answer:
1. 52
2. 2.9
Step-by-step explanation:
To find the mean, we take all the numbers, add them up then divide by the number of numbers.
1. mean height
mean = (50+54+52+56+48)/5
=260/5
=52
52 inches
2. mean score
There are 5+3+12+2+6+6+4 students = 38 students
Multiply the number of students times the score and add together
total points = (0*5+1*3+2*12+3*2+4*6+5*6+6*4)
= 111
The mean is the total points divided by the number of students
mean = 111/38
=2.92
The answer is C
10% = 0.10
12 x 0.10 = 1.20
12 - 1.20 = 10.80
Answer:
The diameter is any straight line that passes through the center of the circle, which endpoints can lie on. The radius is half the diameter. They help us find the circumference of a circle
