Help me please! I’m struggling

For the given triangle, x measures 8.6 cm.

Step-by-step explanation:

Step 1; In the given triangle, the opposite side has a length of x units, the adjacent side has a length of y units while the hypotenuse of the triangle measures 15 units. The angles given are 35° and 90°, this makes the triangle a right-angled triangle.

Step 2; As we have the values of the angle and the hypotenuse, we can calculate the sine of the angle to determine the value of x.

sin 35° = = , sin 35° = 0.57357.

0.57357 = , x = 0.57357 ×  15 = 8.60355 cm.

Rounding this off to the nearest tenth, we get x = 8.6 cm.

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

36/60

36/2=18

60/2=30

18/30

18/3=6

30/3=10

6/10

6/2=3

10/2=5

your final answer would be 3/5 of an

hope this !
