Answer:
x = 25
<B = 120 degrees
<C = 30 degrees
Step-by-step explanation:
Total angle measure of a triangle - 180 degrees
Add all the angles together to find the value of x
30 + 4x + 20 + x + 5 = 180
55 + 5x = 180
55 - 55 + 5x = 180 - 55
5x = 125
x = 25
<B = 4(25) + 20
<B = 100 + 20
<B = 120
<C = 25 + 5
<C = 30

Answer:
x=9
JKL = 108 degrees
KLJ = 27 degrees
LJK = 45 degrees
Step-by-step explanation:
Add all the values of the triangle angles together to get 20. Then divide 180 by 20 to get 9 (The sum of all the angles in the triangle always equals 180 degrees).
JKL = 12x = 12(9) = 108
KLJ = 3x = 3(9) = 27
LJK = 5x = 5(9) = 45
