A suitable solver will tell you instantly that the measure of b is 179.18 ft.

_____
If you want to do it yourself (meaning also with the aid of a calculator), you can use the Law of Sines. The given side is side "c", so you need the measure of angle C. That will be
  180° -33° -63° = 84°
Then side "b" can be found from
  b/sin(B) = c/sin(C)
  b = c*sin(B)/sin(C)
  b = (200 ft)*sin(63°)/sin(84°) ≈ 179.183 ft

Answer:

x = -19; y = 25/3

Step-by-step explanation:

Step 1: solve the equation with only one variable

Isolate the variable (x)

x + 10 = -9

x = -9 - 10

x = -19

Step 2: input new information into the other equation

If x = -19, then:

2(-19) - 6y = 12

Isolate the variable (y)

-38 - 6y = 12

-6y = 12 + 38

-6y = 50

y = 50 ÷ 6

y = 50/6

Simplify

y = 25/3

What is 17/18 + 1/20
MrMuchimi

Answer:

179/180

Step-by-step explanation:

<em><u>Step One</u></em>

Find the prime factors of 18 and 20

18:3*3*2

20: 2 * 2 * 5

<em><u>Step Two</u></em>

You need two 2s two 3s and one 5 for the common denominator

The common denominator is 2 * 2 * 3 * 3 * 5 = 180

<em><u>Step Three</u></em>

Put the two fractions over 180

\dfrac{17*10}{10*18} + \dfrac{1*9}{10*18}

\dfrac{170}{180} + \dfrac{9}{180}

179/180
