Answer:
Step-by-step explanation:
In the multiple you add the power and in the ÷ ye substract the power as in firts one it is 4 power 3+9
Since you have the 42-deg angle and the length of the opposite side, 31, you can use the Law of Sines.
We will use the law of sines first to find x.
Once we know x, we can find the angle opposite y.
Then we can find y.
Let z = the angle opposite y.
z + 42 + 53 = 180
z = 85
It is all real numbers because when graphing it, it would go infinitely in both directions.
Answer:
The perimeter is 56mm
Step-by-step explanation:
N/B: the figure is not given, nevertheless we can infer that the figure is a triangular figure given that the lengths provided is just three.
So the perimeter is the distance around the object.
Perimeter =20+20+16= 56mm
