Answer:
10
Step-by-step explanation:
the formula y = mx +c
the y is obviously, y.
m, also means the gradient has a value of -4
c is the y-intercept, so the value of c is 10.
Try this solution:
dx/siny=dy/cos2x;
sinydy=cos2xdx;
cosy=-1/2 sin2x+C.
Answer:
120
Step-by-step explanation:
The sum of the angles is 180 since it forms a straight line
2x+ x+90 = 180
Combine like terms
3x +90=180
Subtract 90 from each side
3x+90-90=180-90
3x= 90
Divide each side by 3
3x/3 = 90/3
x = 30
We want angle DBC = x+90
= 30+90
=120

Step-by-step explanation:
Answer:
-12
Step-by-step explanation:
h/6 -1 = -3
h - 6 = - 18
h = -18 + 6
h = -12
