Answer:
x=8
Step-by-step explanation:
so since the whole thing should equal 180, and the right triangle is 90,
(3x+11)+(5x+15)=90 then solve for that
8x+26=90
8x=64
divide both sides by 8
so x=8
then plug in 8 for the xs so c is 3(8)+11 --> 24+11 so m<C=35*
m<D=90*
5(8)+15 40+15 so m<E=55
$4.96 is the answer. 2.23 times 2 because it is two clipboards. Then add 0.58. And finally subtract by ten
4X+60=640
4X=640-60
4X=580
X=580/4=145
Answer: x = 7
Step-by-step explanation:
sure thing! so, one angle is 34 degrees, and the other clear angle is 60 degrees. we know that because the angle on the lower shape matches that one. we then just add those, which comes out to 94 degrees. a triangle is 180 degrees, so we subtract 94 from that in order to figure out the total degrees in that last angle. that angle comes out to be 86 degrees. then, we subtract 2 in order to divide easily. we then divide 84 by 12, and we get 7. so, x = 7
Dy/dx = dy/dt * dt/dx
xy = 4
y + x(dy/dx) = 0 by implicit differentiation.
x(dy/dx) = -y
dy/dx = -y/x
<span>dy/dx = dy/dt * dt/dx dy/dt = -2
</span>
<span>-y/x = -2 * dt/dx
</span>
y/(2x) = dt/dx
dt/dx = y/(2x)
dx/dt = 2x/y
When x = -3, xy = 4, y = 4/x = 4/-3 = -4/3
dx/dt = 2*-3/(-4/3) = -6 *-3/4 = 18/4 = 9/2 = 4.5
dx/dt = 4.5
