Answer:x = 56
Step-by-step explanation:
180-(60+64)=56
Answer:
If I had to take an educated guess I'd say 126° but I'm not 100% sure.
First of all, we need to know:
3^3 = 3 x 3 x 3 = 9 x 3 =
27So:
So, your answer is
D.
Theres only 3 shapes that can form such regualr tessellations triangle square and regular hexagon so that being said triangle is your answer
<span>let:
X = the distance of the bottom of the ladder from the wall at any time
dX/dt = rate of travel of the bottom of the ladder = 1.1 ft/sec
A = the angle of the ladder with the ground at anytime
dA/dt = rate of change of the angle in radians per second
X = 10 cos A
dX/dt= -10 sin A dA/dt = 1.1
dA/dt = -1.1/(10 sinA)
When X = 6; cosA = 6/10; sinA = 8/10
Therefore:
dA/dt = -1.1/(10 x 0.8) = -0.1375 radiant per second. </span>
