Can some find the area to this triangle I tried a bunch of things and i keep getting it wrong

The answer to your question is 287.52 u²

Step-by-step explanation:

To calculate the area of a triangle it is necessary to have the base and the high of this figure.

Base = 35 km

height = ?

To calculate the height draw a right triangle and use the trigonometric function sin to find it.

sin Ф =

Opposite side = hypotenuse x sinФ

Opposite side = height = 37 x sin28

                                     = 16.43 km

Calculate the area

              Area = (1/2)(35)(16.43)

             Area = 287.52 u²

b. 24 mm

step-by-step explanation:

use the pythagorean theorem.

a^2 + b^2 = c^2

a^2 + 7^2 = 25^2

a^2 + 49 = 625

a^2 = 576

a = 24

answer: b. 24 mm

answer: 15
