Remark
pi/4 is between 0 and pi/2 which means that pi/4 is in the first quadrant.
5*pi / 4 is between pi and 3/2 pi which means that the angle is in the third quadrant.
So you are talking about one two angles that are in the first and third quadrants.
Step One
Find the Tangent of pi/4 using the unit circle as a reference.
Since pi/4 is 1/2 way between 0 and pi/2 you are referring to something that has and x value of 0.707 for an x value and 0.707 for a y value. (They are equal)
That is the point where the opposite / adjacent = 0.707/0.707 = 1
Step Two
Find the tangent of 5pi/4 using the unit circle.
Using the same argument as pi/4 this time the opposite / adjacent = -0.707/-0.707 = 1 ( the two minus signs cancel out.)
Answer: 8*5
Step-by-step explanation: Because the comutative property says you can like, switch up the orders of the numbers in a thing and it is still trye. So 5*8=8*5.
Answer:
132+54+90=276
360-276= 84
Step-by-step explanation:
a circle has 360° so subtract all the given angles to find the missing one. yu can subtract each one by one or add all the given angles and subtract which I did
0.1 is 1/10 of 0.9
You can divide 0.9 by 0.1
We can rewrite the ratio as x/y=11/8 and z/y=6/7 (division).
Then, solve for y:
y=x/(11:8)=z/(6/7)
y=x times 8/11=z times 7/6
multiply everything by 66, the lowest multiple of 6 and 11
The answer is 48x:66y:77z
