Answer:

x = \frac{\sqrt{10} }{2}

Step-by-step explanation:

Using Pythagoras Theorem:

The triangle has hypotenuse of √10 , opposite side x, angle 30°

Using the formula:

                                   sin(A) = \frac{opposite}{hypotenuse}

                                   sin(30)= \frac{x}{\sqrt{10} }

                                    x = sin(30) * \sqrt{10}

                                    x = \frac{\sqrt{10} }{2}

Answer:

\frac{\sqrt{10} }{2}

Step-by-step explanation:

Using cosine (since that is adjacent over hypotenuse), cos(60)=1/2 so your answer is hypotenuse*1/2=\sqrt{10}*\frac{1}{2}=\frac{\sqrt{10} }{2}

HELP PLEASEEEEE URGENT
gregori [183]

Answer:

5

Step-by-step explanation:

1) Solve for the slope(m):

(y2-y1) / (x2-x1)

pick any

(-3 - (-5) )/ (1 - 0)

(-3 + 5) / (1 - 0)

2/1 = 2

2) b(intercept) value is found when x = 0:

x = 0, y = -5,

b = y

b = -5

3) Plug it in:

y = mx + b

y = 2x - 5

4) when the value is 5, x = 5:

y = 2x - 5

y = 2(5) - 5

y = 10 -5 = 5
