If a right isosceles triangle has an area of 192 cm, what is the height of the triangle?
xxMikexx [17]

The height of the triangle is 19.596 centimeter, if a right isosceles triangle has an area of 192 square centimeters.

Step-by-step explanation:

The given is,

               Area of right isosceles triangle is 192 square centimeters

Step:1

             Formula for area of  right isosceles triangle is,

                                       A=\frac{1}{2} a^{2}............................(1)

            Where, a - Sides of triangle

                         a = h = b

            Here, h - Height of triangle

                      b - Base of triangle

           From given,

                    Area, A = 192 square centimeters

           Equation (1) becomes.

                              192=\frac{1}{2} a^{2}

                                a^{2} = (2)(192)

                                     = 384

                                a^{2} = 384

          Take square root on both sides,

                                 a=\sqrt{384}

                                  a = 19.596 centimeters

         Height of right isosceles of triangle, a = h = 19.596 centimeters

Result:

        The height of the triangle is 19.596 centimeter, if a right isosceles triangle has an area of 192 square centimeters.

8x^2-2x-1=0 find the solution
jek_recluse [69]
8x² - 2x - 1 = 0
8x² - 4x + 2x - 1 = 0
4x (2x - 1) + 1 (2x - 1) = 0
(4x + 1)(2x - 1) = 0

4x + 1 = 0 or 2x - 1 = 0
x = -1/4 0r x = 1/2

It takes 22 minutes to go 1 mile on horseback. at this rate, how long will it take tim to go 6 miles
kondaur [170]

Answer:

132 minutes

Step-by-step explanation:

If you see that 1 mile is 22 minutes, then you would know 2 miles is double, three miles is triple and so on. So you would do 22x6 for the six miles to get your answer of 132, or you can even do 22 plus 22 six times.

PLEASE HELP! <br> m∥n m∠1 = 50°, m∠2 = 48°, and line s bisects ∠ABC What is m∠3 ?
elena-14-01-66 [18.8K]

Answer:

m∠3 = 49°

Step-by-step explanation:

From the picture attached,

lines m and n are the parallel lines and line t is a transversal line intersecting these parallel lines at E and B respectively.

Therefore, ∠DEF ≅ ∠ABC [Exterior alternate angles]

m∠1 + m∠2 = m∠4 + m∠5

m∠4 = m∠5 [line s bisects ∠ABC]

50° + 48° = m∠4 + m∠4

98° = 2m∠4

m∠4 = 49°

Since, ∠4 ≅ ∠3 [Vertically opposite angles]

m∠3 = 49°
