Mathematics
1 answer:
Semmy [17]2 years ago
6 0

Answer:

20 degrees

Step-by-step explanation:

I don't know why the 30 degrees was given at point A because you don't need that.

The equation is;

Sinx=  Opposite/Hypotneuse

     x = Sin inverse (50/146)

        = 20.02

        Rounded to 20 degrees

What is an equation of the line that passes through (-2,3) and is parallel to y=5x + 4.Give your answer in slope intercept form
9966 [12]

Answer:

y= 5x+13

Step-by-step explanation:

<u>Slope- intercept form</u>

y= mx +b, where m is the gradient and b is the y-intercept.

Parallel lines have the same gradient.

y= 5x +4

Gradient of given line= 5

Thus, gradient of line= 5

Subst. m=5 into the equation.

y= 5x +b

To find the value of b, substitute a coordinate

When x= -2, y=3,

3= 5(-2) +b

3= -10 +b

b= 3 +10 <em>(</em><em>+</em><em>1</em><em>0</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>

b= 13

Thus, the equation of the line is y= 5x +13.

the area of a rectangular flower bed is 6.5sq.feet. the width of the flower bed is 0.75 feet. what is the length of the flower?
RSB [31]

width= w

length = l=w+5

Area = l * w

104  =(w+5) * w

w2 +5w -104 =0

(w+13)(w-8)=0

w=13 and w=8

so width =8

length=13
