Answer:
53 degrees
angle DCE is congruent to angle DAE.
Answer:
Step-by-step explanation:
0.00048*.81=0.0003888
0.0003888*10=0.003888
0.003888*(10)=0.3888
0.3888-7=-6.6112
-6.6112*0.027=-224.8592593
-224.8592593*0.04= -9.794370372
-9.794370372*(10)=-97.94370372
-97.94370372*6= -587.6622223

Answer:
Step-by-step explanation:
The derivative of inverse trigonometric identities follow<span> a set of rules. </span>
<span>For </span>arc cos<span> x, the </span>dy/dx is equal to -1/ square root of (1 - x2).
<span>In this case, we still have 1/2 x inside the angle quantity so we multiply the </span>dy/dx above with 1/2. Hence, y' = is -1<span>/ 2 square root of (1 - x2); x = 1, y' is infinity. this means the line is horizontal. The answer hence is y = 1.</span>
