I am not quite sure what the question asks for,
But this is what i assume it wants:
Cos A= 0.6489
In this given one, we basically find the size of the angle A
we do cosine inverse on both sides to get the size of the angle A
: It looks like this in the calculator
× cos A=
(0.6489)
(
and cos cancels out)
A=
(0.6489)
A=49.54°
check:
cos 49.54=0.6489 (its right!)
Answer:
Square with side length 25/4 m
Step-by-step explanation:
The area is always going to be largest for a rectangle when the two dimensions are equal. You are looking for a square. What square has perimeter 25? 4s=25 so the side length of this rectangle (Square) is 25/4 m.
Hey there! I'm happy o help!
To get from 60 to -20, you multiply by -1/3. This is our constant of proportionality. Let's see which points below follow this.
-10(-1/3)=3 1/3≠30
30(-1/3)=-10≠-15
-30(-1/3)=10
80(-1/3)=-26 2/3≠-30
Therefore, the correct answer is (-30,10).
Have a wonderful day! :D
Supplementary means it adds up to 180 degrees.
So if one side is 31 degrees, you would need to subtract that from 180 to find the other side.
-----------------------
180 - 31 = 149
-----------------------
The other angle would be 149 degrees.
