The answer is 3 :) hope this is right
Answer:
3(m+8)
Step-by-step explanation:
first you add m to 8, so you would do m+8. then you triple that, means multiply it by 3. so 3(m+8)
Answer:
distance of diver 1 from the shark ≈ 18.88 m
Step-by-step explanation:
The illustration forms a triangle. The base of the triangle which is their distance apart is given as 30 m . The known angle of the triangle are 52° and 39°. To find the unknown side we subtract the sum of 52° and 39° from 180°. Note that the total angle in a triangle is 180°.
Therefore,
180 - (52 + 39) = 180 - 91 = 89
°. Now the three angle of the triangles are 52°, 39° and 89°.
Using the law of sine we can find the distance of the diver 1 from the shark.
let a = distance of the first diver to the shark.
a/sin 39° = 30/sin 89°
cross multiply
a sin 89° = 30 sin 39°
divide both sides by sin 89°
a = 30 sin 39°/sin 89°
a = 30 × 0.62932039105
/sin 89°
a = 18.8796117315
/0.99984769515
a = 18.8824876258
a ≈ 18.88 m
Answer:
Length of shadow on the ground = 11 ft (Approx)
Step-by-step explanation:
Given:
Height of pole = 15 ft
Angle of elevation of the sun = 53°
Find:
Length of shadow on the ground = ?
Computation:
⇒ Tan A = Height / Base
⇒ Tan A = Height of pole / Length of shadow on the ground
⇒ Tan 53° = Height of pole / Length of shadow on the ground
⇒ Tan 53° = Height of pole / Length of shadow on the ground
⇒ 1.327 = 15 / Length of shadow on the ground
⇒ Length of shadow on the ground = 15 ft / 1.327
⇒ Length of shadow on the ground = 11.3 ft
Length of shadow on the ground = 11 ft (Approx)
