B/sin B = a / sin A
27 / sin B = 32 / sin 48°
sin B = 27sin 48 / 32 = 0.6270
B = arcsin(0.6270) = 39°
C = 180 - 48 - 39 = 93°
c / sin 93° = 32 / sin 48°
c = 32sin 93° / sin 48 = 43

B - 39°, C = 93°, c = 43

What is the radius of the field? *<br> a circular field has a area of 14400 sq ft
Aleonysh [2.5K]

Answer:

r = 67.70 feet

Step-by-step explanation:

Area of circle, A = πr²

where r is the radius and π = 3.142

A = πr²

r² = A / π

r = √(A / π)

r = √(14400 / 3.1042)

r = √(4583.66)

r = 67.70 feet

The slope, m, of a linear equation can be found using the formula m = v2 - v1/x2 - x1 , where the x- and the y-values come from
rusak2 [61]

Answer:

y2 = m(x2-x1)+y1

Step-by-step explanation:

Given the expression;

m = y2-y1/x2-x1

Making y2 the subject of the formula

Cross multiply

m(x2-x1) = y2-y1

Add y1 to both sides

m(x2-x1)+y1 = y2-y1+y1

m(x2-x1)+y1 = y2

Hence y2 = m(x2-x1)+y1

Use this diagram to find the measures of the lengths of the sides. The perimeter of the trapezoid on the right is 97 inches.
irina [24]

Answer: 48 inches, 14 inches, 21 inches and 14 inches.


Step-by-step explanation:

1. The perimeter of the trapezoid is the sum of the lengths of its sides. You know that the perimeter is 97 inches, then, you can write the following expression:

3.5x-1+x+x+1.5x=97\\7x-1=97

2. Now, you must solve for x, as following:

7x=97+1\\7x=98\\x=\frac{98}{7}\\x=14

3. Then length of each side is:

(3.5x-1)in=(3.5(14)-1)in=48in

1.5xin=(1.5)(14)in=21in

x=14in

At 7:00 am, the temperature was 8 c. what was the temperature at midnight if the temperature was 10 lower
GREYUIT [131]

Answer:

The temperature at midnight was: -2 ° C

Step-by-step explanation:

We know the following:

Temperature at 7:00 am = 8 ° C

Midnight temperature: 10 degrees lower than the temperature at 7:00 am

Then the temperature at midnight will be equal to the subtraction of:

8 ° C - 10 ° C

The temperature at midnight was:

8 ° C - 10 ° C = -2 ° C
