Please answer number 1 and number 2 The magnitude of the two force vectors shown

Question

Please answer number 1 and number 2

The magnitude of the two force vectors shown are Fa = 140 lb and Fb = 100 lb. Determine the magnitude Fr and coordinate direction angles (a, beta, gamma) of the resultant of the two vectors. The airplane's engines exert at total thrust force T of 200 kN magnitude. The angle between T and the x axis is 120 degree, and the angle between T and the v axis is 130 degree. The z component of T is positive. What is the angle between T and the z axis? Express T in Cartesian Vector form

Explanation / Answer

2)T=sqrt((Tcos120)^2+(Tcos130)^2+Tz^2)=200*10^3 we get Tz=87.107*10^3N T=[-100i-128.55j+87.107*10^3k]*10^3 plss rate..
