Answer:

  • x = 4.5 units

Step-by-step explanation:

Given is the 30*60*90 right triangle.

<u>Its side ratio is:</u>

  • a : b : c = 1 : √3 : 2, from the shortest to the longest sides

<u>We have:</u>

  • c = 9
  • a = x

<u>Use the above ratios to find the length of a:</u>

  • a : c = 1 : 2
  • x : 9 = 1 : 2
  • x = 9/2
  • x = 4.5

What the equation parallel to y=-1/5x +7 and containing the point(-10,-3)
Agata [3.3K]

The equation of line parallel toy=-\frac{1}{5} x +7 and containing the point(-10,-3) is y=-\frac{1}{5}x-5

Step-by-step explanation:

We need to write the equation parallel to y=-\frac{1}{5} x +7 and containing the point(-10,-3)

The standard form of point slope equation is:

y=mx+b

where m is slope and b is y-intercept

Comparing the given equation  y=-\frac{1}{5} x +7 with standard form the slope is m= -1/5

Since the lines are parallel the slope of new line is m = -1/5

Now finding b (y-intercept)

Using slope m=-1/5 and point (-10,-3)

y=mx+b\\-3=-\frac{1}{5}(-10)+b\\-3=2+b\\b=-3-2\\b=-5

So, b= -5 and slope = -1/5 the equation of new line is:

y = mx+b\\y=-\frac{1}{5}x-5

So, The equation of line parallel toy=-\frac{1}{5} x +7 and containing the point(-10,-3) is y=-\frac{1}{5}x-5

Write an equation for the line in point-slope form.Passing through (5,3) with x-intercept 6
Rama09 [41]

Remember that the point-slope form of a line is:

y-k=m(x-h)

For a line with slope m and that passes through point (h,k)

Now, let's work on the line we're given. SInce the x-intercept is 6, we know that the line passes through (6,0).

Let's calculate the slope m :

m=\frac{3-0}{5-6}\rightarrow m=\frac{3}{-1}\Rightarrow m=-3

Now, using point (5,3) we can get the following point-slope form for the line:

y-3=-3(x-5)

Step-by-step explanation:

am scored 92,25,105,62,65 in 5 matches

The average score per match is

= total of runs in 5 matches/ 5

= 92+25+105+62+65/5

=355/5

= 71

Answer: the average score per match is 71 maybe try looking around before wasting points but im glad to help

Pi/24 is the solution for 4cos2 (4x) - 3 = 0<br><br> True or false
inessss [21]

Answer:

True.

Step-by-step explanation:

Given,

4cos2 (4x) - 3 = 0

Now, 4π/24 = π/6

Or, cos π/6 = √3/2

Or, cos^2 π/6 = 3/4

Or, 4 cos^2 π/6 = 3

Now, Left Hand Side= 4cos2 (4x) - 3

                                  = 3-3 =0 = Right Hand Side (Proved)

Here, Left Hand Side= Right Hanad Side. So, 4cos2 (4x) - 3=0 is true.
