<u>Answer:</u>

  • a = 3.5

<u>Step-by-step explanation:</u>

<u>Let's find 'a' using Pythagoras theorem.</u>

  • => 4² = 2² + a²
  • => 16 = 4 + a²
  • => 12 = a²
  • => a = √12
  • => a = √2 x 2 x 3
  • => a = 2√3
  • => a = 2 x √3
  • => a = 2 x 1.732
  • => a = 3.464 = 3.5 (Estimated)

Hoped this helped.

Special right triangles: what is the value of x? enter your answer in the box.
tiny-mole [99]
I think you meant to add more to your question (posting the specific problem).
In general, one special right triangle is the <span>45°-45°-90° triangle, in which both legs are congruent and the hypotenuse = √2 * the length of the leg. if you happen to not have the length of the leg, the formula for finding the leg is:  leg = hypotenuse / √2

Another special right triangle is the </span><span>30°-60°-90° triangle. With this kind of triangle the length of the hypotenuse is twice the length of the shorter leg. The length of the longer leg is √3 times the length of the shorter leg.
hypotenuse = 2 * shorter leg
longer leg = √3 * shorter leg</span>

Write an equation of the line that passes through (2,-1) and is parallel to the line y = -3x + 8.
Anika [276]

Answer:

y = -3x +5

Step-by-step explanation:

parallel lines so slope of the lines will be equal.

m1 = m2

y = mx + b,

y = -3x + b

substituting y = -1 and x = 2

-1 = -3(2) + b

-1 = -6 + b

therefore, b = -1 + 6

b = 5

by substituting b = +5

therefore, the equation is,

y = -3x + 5

How many solutions does the equation have?
son4ous [18]
The equation would have infinite solutions.
First, distribute on both sides, and you get 12x - 6 = 12x - 6.
There are two ways to do this from here. first is: you add six to both sides and they'll cancel out, and you'll have 12x = 12x. Then you divide by 12 on both sides and get x = x.  When the two sides equal the same thing, there are infinite solutions.
Or, we can do the easy way. As you can see, 12x-6 = 12x-6. Both the sides are clearly the same, so we actually don't need to do the rest.
ANSWER: infinite solutions
