Interior-Angle
Lesson 7.8
Divide the polygon into triangles. Then, multiply the number
of triangles by 180 to find the interior-angle sum for each
polygon.
Answer:
To find the sum of interior angles of a polygon, multiply the number of triangles in the polygon by 180°. The formula for calculating the sum of interior angles is ( n − 2 ) × 180 ∘ where is the number of sides. All the interior angles in a regular polygon are equal.

Answer:
x = 1
y = -2
Step-by-step explanation:
5x - 2y = 9 -----------(I)
2x + 7y = -12 --------------(II)
Multiply (I) by 7 35x - 14y = 63
Multiply (II) by 2 4x + 14y = - 24 {Now add and thus y will be eliminated}
39x = 39
x = 39/39
x = 1
Plugin x = 1 in equation(I)
5*1 - 2y = 9
5 -2y = 9
-2y = 9 -5
-2y = 4
y = 4/-2
y = -2

Find the 80th derivative of f(c)
ET
sin(2).
f(80)
Submit Question
Compute the first few derivatives to reveal a pattern:
f(x) = x sin(x)
f '(x) = x cos(x) + sin(x)
f ''(x) = (-x sin(x) + cos(x)) + cos(x) = -x sin(x) + 2 cos(x)
f '''(x) = (-x cos(x) - sin(x)) - 2 sin(x) = -x cos(x) - 3 sin(x)
f ''''(x) = (x sin(x) - cos(x)) - 3 cos(x)) = x sin(x) - 4 cos(x)
f ⁽⁵⁾(x) = (x cos(x) + sin(x)) + 4 sin(x) = x cos(x) + 5 sin(x)
f ⁽⁶⁾(x) = (-x sin(x) + cos(x)) + 5 cos(x) = -x sin(x) + 6 cos(x)
f ⁽⁷⁾(x) = (-x cos(x) - sin(x)) - 6 sin(x) = -x cos(x) - 7 sin(x)
f ⁽⁸⁾(x) = (x sin(x) - cos(x)) - 7 cos(x) = x sin(x) - 8 cos(x)
and so on.
The pattern should be clear: for some integer k,
• if n = 4k, then f ⁽ⁿ ⁾(x) = x sin(x) - n cos(x)
• if n = 4k + 1, then f ⁽ⁿ ⁾(x) = x cos(x) + n sin(x)
• if n = 4k + 2, then f ⁽ⁿ ⁾(x) = -x sin(x) + n cos(x)
• if n = 4k + 3, then f ⁽ⁿ ⁾(x) = -x cos(x) - n cos(x)
80 is a multiple of 4, so the 80th derivative falls in the first category. Then
f ⁽⁸⁰⁾(x) = x sin(x) - 80 cos(x)

Hypotenuse c = x
Step 2: Solve for x
Substitute in variables [Pythagorean Theorem]: 9² + 7² = x²[Hypotenuse] Rearrange: x² = 9² + 7²[Hypotenuse] Evaluate exponents: x² = 81 + 49[Hypotenuse] Add: x² = 130[Hypotenuse] [Equality Property] Square root both sides: x = √130Find the length of side x in simplest radical form with a rational denominator.

Answer:
a & b=a
Step-by-step explanation:
If a triangles' degrees are 45° 45° and 90°; you have what is called a Special Right Triangle. This is simple and easy to understand with the right equations and setup. Draw yourself a right triangle with side a & b being the same length, label your triangle and angles. I am guessing with the limited question that your side x is either side a or b on your triangle, which means they are both the same length. But if you have a measurement for side c, your hypotenuse, the equation would be: c

Sandy spent half of her allowance going to the movies. She washed the family car and camed 6
dollars. What is her weekly allowance if she ended with 11 dollars?
Answer:
12
Step-by-step explanation:
12 is what she ended with and spent half of the weekly allowance and got 6 for the car wash.

two triangles 1/2(8)(7)=28 each
64+28+28=120
Answer:
88
Step-by-step explanation:
Starting off with 16x4, which isolates the triangle and makes it a little bit easier, you'd get 64, which is the rectangle's area, (I got the 4 from the middle piece). That leaves you with the triangle, which I did 3x8 for, which is 24, usually with triangles you would divide that answer in half because a triangle is only half of the actual area, but since they're two identical triangles, it wasn't necessary.
Twenty five percent of this square is shaded what percent of the square is not shaded
Answer:
75%
Step-by-step explanation:
If 25 percent of a square is shaded, that means that the rest of the square is not shaded. We want an answer that we can add to 25 to get 100. So this means that 75% of the square is not shaded.
