Answer:

365.9 Inches

Step-by-step explanation:

To find the value of Sin A can be found using the sine rule. the rule states that the ratio of the length facing an angle in a triangle to the sine of the angle is constant. As such,

a/Sin A = b/Sin B = c/Sin C

Where is a is the side facing angle A, b is the side facing angle B and c is the side facing angle C.

Hence,

58/Sin 19 = r/Sin 115

r = 58 Sin 115/ Sin 19

= 365.9 Inches

How to graph y=(x+3)^2+4
Karolina [17]

Answer: It will be a positive parabola with it's point at (-3,4)

Step-by-step explanation:

The graph is parabola since x is squared. Anything inside of parentheses with the x will deal with the x axis, with the x axis you have to reverse the sign of the number (positive to negative and negative to positive). Therefore, you go left by 3. Since the 4 is outside of the parentheses, it has to do with the y axis. Wit the y axis you do not have to reverse the sign, so you go up 4.

dimaraw [331]

Answer:

318.6

Step-by-step explanation:

(3x-9) + (x+15) = 180

3x (x+15) -9 (x+15)

4x + 45x - 9x + 6 = 180

40x + 6 = 180

40x = 180 - 6

40x = 174

x = 4.34

(3x-9) = 4.34 * 3x-9 = 4.02

(x+15) = 4.34 + 15 = 19.34

180 - (4.02 + 19.34)

= 180 - 23.36

= 156.64

hope this answer helps!!
