Answer: 2 7/15
Step-by-step explanation: First, you make sure you have the same denominator on both of the fractions.
4/5 turns to 12/15 and 1/3 turns to 5/15
After that, then you do 12/15 - 5/15, which is 7/15.
Now you do 3 - 1.
Your answer should be 2 7/15.
I hope this helps you and I hope you have a blessed day!
It would be Pi feet squared❤️
Answer:
FIGURE 1:
x = 118; y = 96
FIGURE 2:
x = 85; y = 65
Step-by-step explanation:
FIGURE 1:
You know that x = 118 because of the Corresponding Angles theorem.
Because of the Exterior Angle Theorem (triangles), you can then figure out what y is with the following equation: y + 22 = 118 to get y = 96.
FIGURE 2:
In this figure, you first need to determine what the third angle in the bottom right triangle is. Using the Triangle Sum Theorem, you would find that the third angle is 70.
Because of the Vertical Angles Theorem, you know that the third angle in the top left triangle is also 70. With this information, you can now solve for x using the Triangle Sum Theorem to get x = 85.
Now that you know x, you can solve for y. The other 3 angles in the quadrilateral in which y is a part of are 90, 110, and 95. These could be figured out using the Linear Pair Postulate, the Vertical Angles Theorem, and the Linear Pair Postulate respectively. Now you can figure out y by using the Quadrilateral Sum Conjecture to get y = 65.
The circumference of a circle is 2•3.14(Pi)•R(radius) or 3.14(Pi)•D(diamater).
Since we have our diameter, 60, we need to multiply it by Pi.
60Pi is your answer.
I hope this helps!
Answer:
sin^2 A
Step-by-step explanation:
first expand the trigonometry
1(1-cosA)+cosA(1-cosA)
=1-cosA+cosA-cos^2 A
= 1-cos^2 A
from trigonometric identity sin^2 A + cos^2 A= 1
sin^2 A= 1- cos^2 A
=sin^2 A
