Given:
tan x = 3/y
cos x = y/z

Because tan x = sin(x)/cos(x), therefore
sin x = tan(x)*cos(x)
         = (3/y)*(y/z)
         = 3/z

Answer: a) sin x = 3/z

Answer:

1. Infinitely Many Solutions

2. Zero Solutions

3. One Solution ( x = 6 )

Step-by-step explanation:

1.

12x + 8 = 2( 6x + 4 )

12x + 8 = 12x + 8

2.

2( 2x + 1 ) = 4x + 3

4x + 2 = 4x + 3

2 = 3

3.

4( x + 1 ) = 3x + 10

4x + 4 = 3x + 10

x + 4 = 10

x = 6

Hopefully this helps!

Unknown angle problems with algebra <br> Solve x in the diagram below
Alina [70]

Answer:

35

Step-by-step explanation:

Alright this is like a linear pair. All three angles add up to 180; so this is the set up:

40 + 2x + 30 + 40 = 180

2x + 110 = 180

2x = 70

x=35

Can somebody help solve either of these?
Leya [2.2K]
First one:
The circumference of the whole circle is (2π x the radius), 
and 60° is (60/360) = 1/6 of the whole circumference.

Second one:
The area of the whole circle is (π x the radius²), and
the 40° sector is (40/360) = 1/9 of the whole area.

I hope this is enough help.
