Anyone know this?? it’s finding the sine of a triangle!!
LenKa [72]

Answer:

I'm not sure what you want me to answer from this, so I solved for every variable:

Angle A: 83°

Side b: 6.29

Side c: 5.8

Step-by-step explanation:

-----Angle A:

Since the sum of the interior angles of a triangle ALWAYS equal 180°, we can solve for angle A as follows:

A+51+46=180\\A+97=180\\A=83

-----Side b:

Here, we use the sin rule for finding sides, since we know all of the angles as well as one side:

\frac{a}{sin(A)} =\frac{b}{sin(B)} \\\frac{8}{sin(83)} =\frac{b}{sin(51)} \\8.06=\frac{b}{0.78} \\6.29=b

-----Side c:

\frac{a}{sin(A)} =\frac{c}{sin(C)} \\\frac{8}{sin(83)}=\frac{c}{sin(46)} \\8.06=\frac{c}{0.72} \\5.8=c

Let price of one scarf be $x 
Price of the other is 3 more than $x
 Therefore price of the other scarf =$x +3
 The total price she paid = $25.00
 That is, x+x+3=25
  2x+3=25
  2x=25-3
  2x=22
  x=22/2
  x=11
 The price of one scarf is $11 and the price of the other is 11+3=$14
 The price of the expensive scarf =$14.

In one basketball season, Susan threw the ball and it went in the basket 56 times. If 7/8 of the baskets Susan threw were worth
Ket [755]

Answer:

119

Step-by-step explanation:

Divide the number of baskets (56) by the denominator:

56 ÷ 8 = 7

Multiply by 7 to get the amount of 2 point baskets and multiply by 1 to get the amount of 3 point baskets. (they both add up to 56 baskets)

7 × 7 = 49

7 × 1 = 7

multiply the 49, 2 point baskets by 2 and the 7, 3 point baskets by 3 and add them together to get the total points.

49 × 2 = 98

7 × 3 = 21

98 + 21 = 119
