Ireally need with this, i got 13.7 yards as the altitude by using the law of cosines and i found the area of the triangle by using the formula 1/2(side)(side)cos

The length of the altitude is 9.3 yards and

The area of the triangle Δ UVW is 139.3 yd².

Step-by-step explanation:

Given

WU = 22 yd

WV = 30 yd

∠ UWV = 25°

To Find:

Altitude, UM = ?

area of the Δ UVW = ?

Construction:

Draw UM perpendicular to WV, that is altitude UM to WV.

Solution:

In right triangle Δ UWM if we apply Sine to angle W we get

substituting the values we get

Therefore, the altitude from U to WV is UM = 9.3 yd.(rounded to nearest tenth)

Now for area we have formula

The area of the triangle Δ UVW is 139.3 yd². (rounded to nearest tenth)
