Find the lengths, if needed round to the nearest tenth

Mathematics
1 answer:
Elis [28]3 years ago
7 0

Answer:

Step-by-step explanation:

Triangle ABC is a right angle triangle that is made up of 2 right angle triangle.

To determine y, we would apply Pythagoras theorem which is expressed as

Hypotenuse² = opposite side² + adjacent side²

15² = y² + 12²

225 = y² + 144

y² = 225 - 144 = 81

y = √81 = 9

To determine z,

20² = z² + 12²

400 = z² + 144

z² = 400 - 144 = 256

z = √256 = 16

Prove the identity.<br>cosx sin (x+y) - sinx cos(x+y) = siny​
Jet001 [13]

Answer:

In the explanation

Step-by-step explanation:

Going to start with the sum identities

sin(x+y)=sin(x)cos(y)+sin(y)cos(x)

cos(x+y)=cos(x)cos(y)-sin(x)sin(y)

sin(x)cos(x+y)=sin(x)cos(x)cos(y)-sin(x)sin(x)sin(y)

cos(x)sin(x+y)=cos(x)sin(x)cos(y)+cos(x)sin(y)cos(x)

Now we are going to take the line there and subtract the line before it from it.

I do also notice that column 1 have cos(y)cos(x)sin(x) in common while column 2 has sin(y) in common.

cos(x)sin(x+y)-sin(x)cos(x+y)

=0+sin(y)[cos^2(x)+sin^2(x)]

=sin(y)(1)

=sin(y)
