Answer:
m<JKD = 22 degrees
Step-by-step explanation:
21x + 5 + 4x + 2 = 132
25x + 7 = 132
25x = 125
x = 5
m<JKD = 4x + 2
4(5) + 2
20 + 2
22
Answer:
Step-by-step explanation:
All of the res ones are congruent. HJ is too because <HBJ is also 98 degrees because of vertical angle theorem. Hope this helps!
