Each number contains a different amount than others.
Answer:
43.60°
Step-by-step explanation:
We can solve the triangle using the trigonometrical ratios which may be expressed in the form SOA CAH TOA Where,
Sin Ф = opposite side/hypotenuses side
Cosine Ф = adjacent side/hypotenuses side
Tangent Ф = opposite side/adjacent side
The hypotenuse is the side facing the right angle while the opposite is the side facing the given angle.
Considering triangle ΔDEF, where ∠F=90°, FE = 21, DF = 20, and ED = 29
As such, with respect to angle E, ED is the hypotenuse, DF is the opposite side and FE is the adjacent side
Cosine ∠E = 21/29
∠E = cos-1 0.724137931
∠E = 43.60° to the nearest hundredth
Step-by-step explanation:
1=78°
3= 78°
4= 360°- 78° - 78°
= 204° ÷ 2
= 102°
2= 102°
Note that 1+2+3+4=360°
180° - (4)
= 180° - 102°
= 78° ÷ 2
= 39°
ans; angle ACD is 39°
Answer:
So the answer is the OA :P
Step-by-step explanation:
This means that when the force is applied on a body and the displacement of the body takes place in the direction of the force applied then work done is maximum. So when theta=0°, work done is maximum. !
