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:
√869 ≈ 29.48 square units
Step-by-step explanation:
The vector cross product is ...
(3·1 -5·4, -6·1 +2·4, 6·5 -2·3) = (-17, 2, 24)
The area is the magnitude of this vector, so is ...
√((-17)² +2² +24²) = √(289 +4 +576) = √869 ≈ 29.48
The area is about 29.48 square units.
