Step-by-step explanation:
u see,
the height of the airplane from the ground is 314m
but with the tower's horizontal plane, it would be
=> altitude of aircraft - height of tower
=> 314 - 70 = 244 m
now in the ABC,
using the ratio of sine,
sin 16 = AB/AC
=> 0.275 = 244/AC
=> AC = 244/ 0.275
=> AC = 887.9...
=> AC = approx. 886 meters
Answer:
Step-by-step explanation:
First problem:
blank 2) on the left: PR = PQ + QR
blank 3) on the right: Replace PR in statement 1) with what we just completed in statement 2. Therefore:
2PQ = PR
2PQ = PQ + QR
blank 4) on the right: Subtract PQ from both sides, therefore
2PQ = PQ + QR
2PQ - PQ = PQ + QR - PQ
PQ = QR
Answer:
w = -19
Step-by-step explanation:
-6w + 4(w +3) = 26
-6w + 4w + 12 = 26
simplify
-2w + 12 = 26
now get the variable and the numbers on different sides
-2w + 12 - 12 = -2w
26 + 12 = 38
-2w = 38
now divide each side by -2
-2w / -2 = w
38 / -2 = -19
w = -19
