law of sineslaw of cosinesPythagorean theoremarea formulaStep-by-step explanation:
The method for finding the unknown length of a side of a triangle depends on what other information is given. In general, you need one side, one angle, and at least one other side or angle.
Solving a triangle usually is introduced with the Pythagorean theorem. For a right triangle, it tells you ...
the square of the hypotenuse is equal to the sum of the squares of the other two sides.
If the side lengths are a, b and the hypotenuse is c, then ...
c² = a² + b²
Solving for the hypotenuse, c, you have ...
c = √(a² +b²)
Solving for one side, a, you have ...
a = √(c² -b²)
__
Occasionally, you're asked to find a measure of a triangle using the formula for area.
A = 1/2bh
Solving for the base or height gives you ...
b = 2A/h
h = 2A/b
__
Once you learn trigonometry, additional methods are available for solving triangles. The Law of Sines tells you ...
a/sin(A) = b/sin(B) = c/sin(C)
where angles A, B, C are opposite sides a, b, c, respectively.
And the Law of Cosines tells you ...
c² = a² +b² -2ab·cos(C) . . . . . . . . where sides and angles are as above
This can be rearranged by interchanging a, b, c, keeping the appropriate angle. For C = 90°, this reduces to the Pythagorean theorem.
For right triangles, the various trig relations can also be used to solve triangles. These are conveniently summarized in the mnemonic SOH CAH TOA. It is intended to remind you ...
Sin = Opposite/HypotenuseCos = Adjacent/HypotenuseTan = Opposite/Adjacent__
In summary, depending on the given information, you choose an applicable formula, fill in the given information, and solve for the unknown. If you have more than one unknown, you may need to choose a different formula.

Answer:
B) 114.511m^3
Step-by-step explanation:
Formula of a cylinder is πr^2 x h
r = radius (half of diameter)
h = height
Since it is 3/4 full you only do 3/4 of the height so- 0.75 x 9.60 which equals 7.2
Half of the diameter is 2.25. 2.25^2 = 5.0625.
The volume of the cylinder = 5.0625π x 7.2
By solving this, you will get approximately 114.511 m^3 as your answer.

What is the degree of 25 = 2.03 + 2.0 4x + 1
Answer:
Fraction: x = 2197/204
Decimal: 10.76960
Step-by-step explanation:
Switch Sides: 2.03 +2.04x + 1=25
Group Like Terms: 2.04x + 2.03 + 1 =25
Add The Numbers 2.03 + 1 = 3.03: 2.04x + 3.03 = 25
Multiply Both Sides By 100: 2.04 * 100 + 3.03 * 100 = 25 * 100
Clarify: 204x+303=2500
Subtract 303 From Both Sides: 204x + 303 - 303= 2500 - 303
Divide Both Sides By 204: 204x/ 204, 2197/204
Simplify: x = 2197/204

The side AC of the triangle is included between angles A and C.
What is an Included Side?An included side is a side that is in between two angles in a triangle, where the rays of the angles overlap.
Given is a triangle, we need to determine the angles which includes the side AC,
Since angle A and angle C forms side AC, AC is included between: A. ∠A and ∠C.
Thus, in triangle ABC, side AC lies in between angle A and angle C.
Therefore, since angle A and angle C forms side AC, AC is included between ∠A and ∠C.
Hence, the side AC of the triangle is included between angles A and C.

Answer:
305.5 sq inches
Step-by-step explanation:
A (trapezoid) = 1/2·h·(sum of bases)
A = 1/2(17)(8 + 23)
A = 8.5(31)
A = 263.5
A(triangle) = 1/2·b·h
A = 1/2·(6)·(17-3)
A = 3(14)
A = 42
Total Area = 263.5 + 42.0 = 305.5 sq in

please help i’ve done a (5x) but i need b) and c)
Answer:
b would be 6xy
c would be 6xy as well
Step-by-step explanation:
Not really sure how to explain it, I just know it
Answer:
b) 6xy
c) 6xy
Step-by-step explanation:
b) 6 × x × y
Since there are no like terms, just straight away remove the multiplication signs. So the answer is:
= 6xy
c) 2 × x × 3 × y
2 and 3 are like terms since they are both natural numbers (positive integers), you can multiply 2 with 3. The answer will be:
= 6xy

Caitlin drew a circle and labeled the circle S. The diameter of Caitlin’s circle is 12 m. Which of the following best represents the area of Caitlin’s circle?
A. 452 m^2
B. 38 m^2
C. 113 m^2
D. 75 m^2
Answer:
C
Step-by-step explanation:
Radius: 12 / 2 = 6 m
Area: 6^2 x pi = 113 m^2
Answer:
c
Step-by-step explanation:
area = π · r²
to change the diameter to radius you just divide by 2
12/2=6 so the radius is 6
then we just plug 6 into r for the circle are formula
6²=36
36x3.14=113.04 so her best answer choice is c
y=-2(x + 1)2+3
write in standard form
y = -2(x + 1)² + 3
y = -2(x² + 2x + 1) + 3
y = -2x² - 4x - 2 + 3
y = -2x² - 4x + 1
Answer:
4x + y = -1
just simplify then re-write

Solve each equation for y. Use the given values for x to find the values for y. Write answers as ordered pairs.
Answer:
1. x =-4 (-4,27)
x =0 (0,3)
x = 2 (2 , -9)
2. x = -1 (-1 , 3)
x = -2 (-2 , 2)
x = -3 ( -3, 1)
3. x = -3 (-3 , 13)
x = 1 (1 , 1)
x = -2 ( -2, 10)
4. x =2 (2 , 24)
x = 3 (3 , 30)
x = -2 (-2 , 0)
5.x = -3 (-3 , -2)
