Answer:
cos (theta) = √21/5
Step-by-step explanation:
sin (theta) = 2/5
(sin (theta))^2 = 4/25
4/25 + (cos (theta))^2 = 1
(cos (theta))^2 = 1 - 4/25 = 21/25
cos (theta) = √21/5
.) TRAnsitive; think like aTRAin. the cars are connected...
<span>N is connected to X and X is connected to C, so N is connected to C </span>
<span>2)reflexive; think refection, like a mirror, </span>
<span>3)substitution; substituted 40 for mB </span>
<span>4)division prop of eq; both sides of equation divided by 4 </span>
<span>5)AB = 25 - CD; subtracted CD from both sides</span>
