63 + 22 = 85
180 - 85 = 95

An obtuse triangle is a triangle<span> in which one of the </span>angles<span> is an </span><span>obtuse angle
</span>obtuse angle is less than 180 and greater than 90

so answer is

obtuse triangle

Write the point-slope form of the equation of the line that passes through the point (-1, 5) and has a slope of -1.

Anastaziya [24]

Point slope form = y - y1 = m (x - x1)

y - 5 = -1 (x -(-1))
y - 5 = -1 (x+1)

Hope this helps :)

Using the following equation, find the center and radius of the circle. You must show all work and calculations to receive credi

adoni [48]

Answer:

$r = 4$

The center is:

(2, -4)

Step-by-step explanation:

We have the following equation

$x^2 - 4x + y^2 + 8y = -4$

The general equation of a circle has the following form

$(x-h)^2 + (y-k)^2 = r^2$

Where r is the radius and the point (h, k) is the center of the circle

To transform the given equation in the general equation of a circumference we must use the method of square completions

Step 1

$(x^2 - 4x) + (y^2 + 8y) = -4$

<u>Step 2</u>

<u> </u>Add and subtract $(\frac{b}{2})^2$ For an equation of the form

$ax^2 +bx +c$

$(x^2 - 4x +4)-4 + (y^2 + 8y +16) -16= -4$

<u>Step 3 </u> Factor the expressions within the parentheses

$(x-2)^2-4 + (y+4)^2 -16= -4$

<u>Step 4 Simplify</u>

$(x-2)^2 + (y+4)^2= -4+16+4$

$(x-2)^2 + (y+4)^2= 4^2$

Finally

$r = 4$

The center is:

(2, -4)

Lina used 75 square inches of fabric to make a triangular pennant to take to football game.The base of the pennant was 6 inches.

Dennis_Churaev [7]

Answer:

25 inches

Step-by-step explanation:

A triangle is a three-sided polygon with three edges and three vertices. the sum of angles in a triangle is 180 degrees

Area of a triangle = 1/2 x base x height

75 = (1/2) x 6 x height

height = (75 x 2) / 6 = 25 inches
