Answer:
Correct choice is C. Similar AA.
Step-by-step explanation:
We have been given a picutre of the triangles. Using those information we need to find the correct choice.
Consider triangle FGH and triangle JKL.
∠F≅∠J {Both are equal to 30°}
∠H≅∠L {Both are equal to 50°}
Then triangle FGH is similar to the triangle JKL by AA - similarity of the triangle. Because we are getting two congruent angle pairs.
Hence correct choice is C. Similar AA.
Answer:
(n-1)/2n
Step-by-step explanation:
½(1 - 1/n)
(n-1)/2n
F1 . . . 100% of it = 900N is in the +x direction.
F2 . . . 70.7% of it (cos45°, 530.3N) is in the +x direction,
and 70.7% of it (sin45°, 530.3N) is in the +y direction.
F3 . . . 80% of it (520N) is in the -x direction,
and 60% of it (390N) is in the +y direction.
Total x-component: 900 + 530.3 - 520 = 1,950.3 N
Total y-component: 530.3 + 390 = 920.3 N
Magnitude of the resultant = √ (x² + y²)
= √(1950.3² + 920.3²)
= √4,650,070.09
= 2,156.4 N .
Angle of the resultant, measured counterclockwise
from the +x axis, is
tan⁻¹ (y / x)
= tan⁻¹ (920.3 / 1950.3)
= tan⁻¹ (0.4719)
= about 25.3° .
