Suppose that a polygon has ‘n’ sides, then it is to be divided into (n - 2) triangles.

We know that, the sum of the interior angles of a triangle = 180°.

Therefore, the sum of the angles of (n - 2) triangles = 180 × (n - 2)

= 2 × 90 × (n - 2)

= 2 right angles × (n – 2)

= 2(n – 2) right angles

= (2n – 4) right angles

Therefore,

the sum of interior angles of a polygon having n sides is (2n – 4) right angles.

Hence,

the sum of the interior angles of a pentagon (n = 5)

= (2n - 4) right angles

= (2 × 5 - 4) × 90°

= (10 - 4) × 90°

= 6 × 90°

= 540°

131 + 108 + 107 + 110 + x = 540

456 + x = 540

x = 540 - 456

x = 84°

The slope f '(x) at each point (x, y) on a curve. y = f (x) is given along with a particular point (a, b) on the curve. Use this

Advocard [28]

Answer:

Step-by-step explanation:

Integrating each term with respect to x, we get:

x^3 x^2

f(x) = 9--------- + 4------- - 4x + C

3 2

We are told that if x = 0, f(x) = -7, and so C must equal - 7.

The solution is

x^3 x^2

f(x) = 9--------- + 4------- - 4x - 7, or f(x) = 3x^3 + 2x^2 - 4x - 7

3 2

Plzzzzz help me on this and explain

Galina-37 [17]

The Answers are B and C
Its B because 12 is MORE than twice as much as M. Meaning 140 is larger than 2*m
Its C because again it is MORE than twice as much as M. Meaning that 140 is larger than 2m.

Answers;B,C
Hope this helped!

Problem Page Alonzo will rent a car for the weekend. He can choose one of two plans. The first plan has an initial fee of $49.98

igomit [66]

You would start with the equation:Let m=number of miles

49.98+0.12m=35.98+0.17m

Then solve for m

You would then get

49.98+0.12m=35.98+0.17m
-0.12m -0.12m
49.98=35.98+0.05m
-35.98 -35.98
14 = 0.05m
---- --------
0.05 0.05

280=m

What is the value of 2 thirds + 3 fourths

inn [45]

Step-by-step explanation:

⅔ + ¾

→ make the denominator equal of both the fraction

= 2/3 × 4/4 = 8/12

= 3/4 × 3/3 = 9/12

hence,

8/12 + 9/12

= 8 + 9/12 = 17/12

$\frac{17}{12} or \: 1 \frac{5}{12}$

hope this answer helps you dear...take care
