Difficult Math. Up to the challenge?
saw5 [17]

Answer:

We have the three angles of a triangle as an equation, so we can add them together, and they equal 180.

So:

4x+10+12x-6+3x+5= 19x+9=180

19x=171 ... so: x= 171/19 = 9.

So ABC = 102 .. Obtuse angle

BAC = 46 .. Acute angle

BCA = 32 .. Acute Angle

Edit:

Angle 1 = 180 - BAC = 180 - 46 = 134

Angle 2= 180 - ABC = 180 - 102 = 78

A square is inscribed in a right triangle with leg lengths 6 and 8 such that they have a common right angle. find the square's s
DaniilM [7]

The square's side length is 24/7 or 3.428 units if the square is inscribed in a right triangle with leg lengths 6 and 8 such that they have a common right angle.

<h3>What is a right-angle triangle?</h3>

It is a triangle in which one of the angles is 90 degrees and the other two are sharp angles. The sides of a right-angled triangle are known as the hypotenuse, perpendicular, and base.

First we have to find the line that goes through the points (0, 6) and (8, 0)

(y - 0) = (0-6)/(8-0)(x-8)

y = (-6/8)[x - 8]

Plug y = x

x = (-6/8)[x - 8]

After solving:

x = 24/7 or 3.428

y = 24/7 or 3.428

Thus, the square's side length is 24/7 or 3.428 units if the square is inscribed in a right triangle with leg lengths 6 and 8 such that they have a common right angle.
