Find x-component of vector v⃗ =(250m/s , 30∘ above + x-axis)

Firlakuza [10]

We have to calculate the x- component of vector v = 250 m/s.
α = 30° ( above the x-axis ):
v x = v · cos α
v x = 250 m/s · √3/2 = 250 m/s · 0.866 = 216.5 m/s
Answer:
v x = 216.5 m/s

Answer:

ΔFHK and ΔGHJ are the similar triangles by SAS similarity theorem.

Step-by-step explanation:

Picture for the given question is missing; find the picture attached.

If $\frac{\text{FH}}{\text{GH}}=\frac{\text{HK}}{\text{HJ}}$ and ∠H ≅ ∠H

Then ΔFHK ~ ΔGHJ

$\frac{\text{FH}}{\text{GH}}=\frac{\text{HK}}{\text{HJ}}$

$\frac{(12+10)}{10}=\frac{(15+18)}{15}$

$\frac{22}{10}=\frac{33}{15}$

$\frac{11}{5}=\frac{11}{5}$

Since, $\frac{\text{FH}}{\text{GH}}=\frac{\text{HK}}{\text{HJ}}$ and ∠H ≅ ∠H [By reflexive property]

Therefore, ΔFHK and ΔGHJ are the similar triangles by SAS similarity theorem.

Option (3) will be the answer.
