Answer:
4/5
Step-by-step explanation:
<u>Given </u><u>:</u><u>-</u><u> </u>
- A right angled triangle with sides as 3 , 4 and 5 cm .
We need to find the value of sin(β) in the given triangle . We know that the ratio of sine is ,
sin(β) = p/h
- Where p is perpendicular and h is hypontenuse.
sin(β) = 4/5
<h3>Hence the required answer is 4/5.</h3>

Answer:
uhhh maybe c, i thinkkk
Step-by-step explanation:
Use the substitution method
use the first equation, let y = k - x
plug y = k - x into the second equation
==> 2x + 3(k - x) = k + 1
==> 2x + 3k - 3x = k + 1
==> -x = k - 3k + 1
==> -x = -2k + 1
==> x = 2k - 1 is the answer
