Answer:
Sin0= y/r
X= -4 and r= 9 (radius is also the hypotenuse)
In quadrant II y is positive
X^2 +y^2 = r^2
-4^2 + y^2 = 9^2
16 + y^2 = 81
Y^2 = 81-16
Y^2 = 65
Y= sqrt65
Sin0= sqrt65/9
Step-by-step explanation:
If one Angle is = 30
And the other two angles are equal
Given: x = l
ATQ
⇒30+x+l= 180
⇒x + x = 180-30
⇒2x = 150
⇒x = 150/2
⇒x = 75
Therefore x = 75
And the angles are 30, 75 and 75

Step-by-step explanation:
e
W = 120 + 5(h - 30) <== ur equation....where w = total wages earned and h = number of hrs worked
** I got the 120 from (30 hrs * $ 4 per hr) = $ 120
