A triangle has two angles with measures 43 and 51.

1 answer:

6 0

In Euclidean geometry, the angles of a triangle add to 180, which means the remaining angle has a measure of 86 degrees.

In spherical geometry, it's impossible to know the measure of the remaining angle precisely without knowing any more info about the triangle. The sum of the interior angles is between 180 and 540 degrees, so the missing angle is somewhere between 87 and 445 degrees.

Circumference + perimeter =38
x = circumference of circle
find r in terms of x
2 $\pi$ r=x
r= $\frac{x}{2 \pi }$
Area= $\pi$ r^2
so..
A= $\pi$ ( $\frac{x}{2 \pi }$ )^2
= $\pi$ ( $\frac{x^{2} }{4 \pi ^{2} }$ )
= $\frac{x^{2} }{4 \pi }$

(38-x) is perimeter
then
$\frac{38-x}{4}$
( $\frac{38-x}{4}$ )^2
$\frac{x^{2} }{4 \pi }$ + ( $\frac{38-x}{4}$ )^2
then you graph it and it equals
16.716 cm the circumference of the circle

Multiply: (x+4)(x^2+2x+3) <br> Simplify and write your answer in Standard Form.

Oxana [17]

Answer:

x^3+6x^2+11x+12

Step-by-step explanation:

(x+4)(x^2+2x+3)

=x(x^2+2x+3)+4(x^2+2x+3) [by multiplying with bith sides]

=x^3+2x^2+3x+4x^2+8x+12

=x^3+2x^2+4x^2+3x+8x+12

=x^3+6x^2+11x+12

If Y varies directly with X, and Y = -5 and X = 7, what is X when Y = -85?

Tasya [4]

Answer:

X = 119

Step-by-step explanation:

Step 1: Given

Y = -5 X = 7

Y = -85 X = n

Step 2:

-85 ÷ -5 = 17

Step 3:

17 × 7 = 119

Answer:

Y = -5 X = 7

Y = -85 X = 119

n = 119
