Answer:

Sine of an angle =

opposite / hypotenuse

I this figure

AB is the opposite which is 12

BC is the hypotenuse which is 13

sine ∅ = 12/13

Therefore the sine ratio of the angle is

12/13

Hope this helps

4. A river tour boat is going down a stream to a park for lunch and then back up. It is a 60-mile round trip. On

DiKsa [7]

Answer:

The speed of the boat in still water is 10 miles / hour

Step-by-step explanation:

The trip there, and the trip back are the same -- 30 miles

Let the rate of the boat = x

Let the rate of the water = y

30 = 2*(x + y)

30 = 6*(x - y)

Divide the top equation by 2

Divide the bottom equation by 6

15 = x + y

<u>5 = x - y </u> Add the equations together.

20 = 2x Divide by 2

20/2 = x

x = 10

In JKL and PQR, if JK PQ, KL QR, and K Q, then JKL must be congruent to PQR.

Pavlova-9 [17]

True!

Two shapes are congruent if when turning, flipping or sliding one shape it can become another. This problem is illustrated in the Figure below. So, you can see that we have two triangles ΔJKL and ΔPQR. As you can see:

JK=PQ
KL=QR
∠K=∠Q

Given that two sides are equal to two other sides and one angle is equal to another one, then JL= PR. Accordingly, since all the sides are congruent, then the whole triangle JKL is congruent to PQR
