Answer:
Step-by-step explanation:
recall law of Sines :) the same as before Sin(A) /a = Sin(B) / b
[ when you see it a lot.. you'll remember it :D ]
for this problem Z =A=123 and a = 30
Y=B and b =14
Sin(123) / 30 = Sin(B) / 14
14 * 0.0279556 = Sin(B)
0.391379 = Sin(B)
arcSin(0.391379 ) = arcSin ( Sin (B) )
23.040 = B
Y = 23.0°
are you seeing how to do these? so you could on a test?

Step-by-step explanation:
Answer:
The y-intercept is -15.
Step-by-step explanation:
y - 5 = 5(x - 4) is our equation in point-slope form.
point slope form is = y - y1 = m( x - x1)
So, we know that the slope is 5 and one point is (4, 5)
We can use this point and the slope to find the y -intercept.
y = mx + b is slope intercept form.
Let's input the values we know to find the y-intercept.
5 = 5(4) + b
5 = 20 + b
-15 = b
The y-intercept is -15.
