Geo please help I have two question!
cricket20 [7]

Answer:

Step-by-step explanation:

From the given right angle triangle,

the hypotenuse of the right angle triangle is 13

With m∠65° as the reference angle,

y represents the adjacent side of the right angle triangle.

x represents the opposite side of the right angle triangle.

To determine the value of x, we would apply the sine trigonometric ratio which is expressed as

Sin θ = opposite side/hypotenuse. Therefore,

Sin 65 = x/13

x = 13Sin65 = 13 × 0.906

x = 11.8 to the nearest tenth
