4.256 times 10 to the seventh power
Answer:
x = 9
∠B = 7 x 9 - 1 = 62°
∠BCD = 120°
Step-by-step explanation:
exterior angle of a triangle is equal to the sum of two opposite interior angles
∠BCD = ∠CBA + ∠BAC
10x + 30 = (7x - 1) + (58)
10x + 30 = 7x + 57
3x = 27
x = 9
∠B = 7 x 9 - 1 = 62
∠BCD = 10 x 9 + 30 = 120
Answer:
KL=14
Step-by-step explanation:
TU is the middle line.
TU=(KL+JM)/2
2×TU=KL+JM
KL=2×TU-JM=2×23-32=46-32=14
Add up the legnths of the cable then multiply by 1.5
35+50=85
85 times 1.5=127.5
the answer is $127.50
