Using a vector triangle, cosine law, and sine law, determine the resultant of the forces shown in the Figure below. 40 KN ت 50° 10° 30 kN A. The resultant of the two forces, R, is given by 402+302-2(40) (30) cos 130° kN and the direction of the resultant is 30 kN - sin 130° 60°-sin R counterclockwise from the positive x-axis OB.

COSINE LAW * A strip of 640 sq. meters is sold from a triangular field whose sides are 96, 72, and 80 meters. The strip is of uniform width “h" and has one of its sides parallel to the longest sides of the field. Find the width of the strip.

Graph this vector and solve for what is unknown in the problem. 1. Using sine and cosine law compute for the Resultant and the angle that R makes with the horizontal. Given vectors: V1 = 3 m, N and V2 = 4 m, 30 degrees N of E. please use the sine and cosine law in solving

3.14| A certain light-emitting diode (LED) is centered at the origin with its surface in the xy plane. At far distances, the LED appears as a point, but the glowing surface geometry produces a far-field radiation pattern that follows a raised cosine law: that is, the optical power (flux) density in watts/m² is given in spherical coordinates by Pa = Po cos² 0 a, watts/m? 2nr2 where 0 is the ...

Please explain cosine law first then solve the question. Provide handwritten answer only. no typed answer needed Transcribed Image Text: Q16: Find angle B for the roof truss shown in the figure below.

State the Sine Law and Cosine Law equations. Which one did you use more in this project? Whv? Can we use the Cosine Law on right triangles as well? Show that this equation can be reduced to Pythag- orean's Theorem for triangles with a right angle.

Using sine and cosine law compute for the Resultant and the angle that R makes with the horizontal. Given vectors: V1 = 3 m, 30 degrees N of E. V2 = 4 m, 30 degrees N of E.

An airplane has a ground velocity of 400 km/h, [N60°W]. The plane is affected by a 90 km/h wind which is coming from the direction [N80°E]. Determine the magnitude and the direction of the airspeed vector. Please draw the original vectors on a grid and rearrange them properly. The cosine law and the law of sines is suggested.
