17. Find the degree measure of each angle on the triangle (giving BRAINLY to best answer and points)

EleoNora [17]

Answer:

A = 56

B = 62

C = 62

Step-by-step explanation:

Because it is a isosceles triangle with base BC so B=C

Then just calculate it out:

(5x + 26) + (3x + 44) + (3x + 44) = 180

11x + 114 = 180

11x = 66

x = 6

Then put x to A, B, C in the picture

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

zalisa [80]

Answer:

The circle is of radius $5$ and is centered at $(-1,\, -2)$ .

Step-by-step explanation:

Equation for a circle of radius $r$ ( $r > 0$ ) and center $(a,\, b)$ :

$(x - a)^{2} + (y - b)^{2} = r^2$ .

Expand and rearrange to obtain an equivalent equation:

$\left(x^2 - 2\, a\, x + a^{2}\right) + \left(y^2 - 2\, b\, y + b^2\right) = r^{2}$ .

$x^2+ (-2\, a)\, x + y^2 + (-2\, b)\, y = r^2 - (a^2 + b^2)$ .

Compare this equation with the equation of the circle in this question:

Coefficient of the $x$ term: $2$ in the original equation, $(-2\, a)$ in the proposed equation.
Coefficient of the $y$ term: $4$ in the original equation, $(-2\, b)$ in the proposed equation.
Constant term: $20$ in the original equation, $\left(r^2 - \left(a^2 + b^2 \right)\right)$ in the proposed equation.

Assume that the proposed equation matches the equation from the question. Each of the coefficients should match.

From the coefficient of the $x$ term and the $y$ term: $a = -1$ and $b = -2$ .

Hence, the center of this circle is at $(a,\, b) = (-1,\, -2)$ .

The constant term of the two equations should also match: $\left(r^2 - \left(a^2 + b^2 \right)\right) = 20$ .

$\left(r^2 - \left((-1)^2 + (-2)^2 \right)\right) = 20$ .

$r^2 = 25$ .

$r = 5$ (given that radius $r > 0$ .)

Hence, the radius of this circle would be $5$ .

Find the square inches in fabric that is 60 in. wide and 3 ft. long.

Rashid [163]

"Square inches" means area, so 60" wide and 3 feet long is multiplied, however, they have to be in the same unit. So, 3 feet = 36 inches since 1 foot is 12 inches and 3(12) = 36.

Therefore, 60 inches * 36 inches = 2,160 square inches of fabric.

19. Each deli sandwich made uses :- pound of turkey Tyler started with 318 pounds of turkey and now has 1 3 pounds left. How man

sweet [91]

So convert to inprompery fractions
3 and 7/8=3+7/8=24/8+7/8=31/8
1 and 5/8=1+5/8=8/8+5/8=13/8

so each uses 1/4 cup
1/4=2/8
so
find the difference between 31/8 and 13/8

$\frac{31}{8}-\frac{13}{8}$ = $\frac{18}{8}$
so find how many 2/8 goes into 18/8
2/8 times what=18/8
multily both sides by 8/2 to clear faction
what=144/16=36/4=9/1=9
I made 9 sandwitches
