Anyone know the answer?
yan [13]

Answer:

0.

Step-by-step explanation:

The angle whose sine is 5/12 = 22.62 degrees and in Quadrant II it is

180 - 22.62 degrees

The angle whose tan is (5/12)  = 22.62.

So we can write  α as 180 - α  and β as α.

sin (α+β) = sin ( 180 - α = α) = sin 180

= 0.

Solve for x<br><br> 2x - 1 - 1 = x - 3 - ( -5 + x )
Nana76 [90]

Answer:

x=2

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

2x−1−1=x−3−(−5+x)

2x−1−1=x−3+−1(−5+x)(Distribute the Negative Sign)

2x−1−1=x+−3+(−1)(−5)+−1x

2x−1−1=x+−3+5+−x

2x+−1+−1=x+−3+5+−x

(2x)+(−1+−1)=(x+−x)+(−3+5)(Combine Like Terms)

2x+−2=2

2x−2=2

Step 2: Add 2 to both sides.

2x−2+2=2+2

2x=4

Step 3: Divide both sides by 2.

2x

2

=

4

2

x=2
