Answer:
Dont knowwwwwwww
Step-by-step explanation:
Let the longest side of the triangle be x, then the length of one of the other sides of the triangle is 0.5x and the length of the third side is x - 10.
Then, x + 0.5x + x - 10 = 70
2.5x = 80
x = 80 / 2.5 = 32
Therefore, the length of the sides of the triangle are: 32, 0.5(32) = 16 and 32 - 10 = 22.
i.e. 32, 16, 22
Answer:
84.26° in the south west direction.
Step-by-step explanation:
I've attached an image showing the triangle formed by the motion of the plane and the wind.
I've depicted the plane being pushed west and the wind moving south west.
Thus, the direction of motion of the plane will be angle θ.
Using trigonometric ratios;
25/250 = cos θ
cos θ = 0.1
θ = cos^(-1) 0.1
θ = 84.26°
Thus will be in the south west direction.
His average speed for the rest of the journey was of 48mph.
