Find the value of x in the isosceles triangle shown below.
guajiro [1.7K]

Answer:

B) x = \sqrt{60}

Step-by-step explanation:

1. As you can see from the image, there are two right triangles in the isosceles triangle. The base of each right triangle is 2 (because 4 ÷ 2 = 2), and the hypotenuse is 8.

2. Let's use Pythagorean Theorem to find the height of each right triangle, which will also give us the height of the isosceles triangle: a^2 + b^2 = c^2, where a = height, b = base, and c= hypotenuse.

  • a^2 + 2^2 = 8^2
  • a^2 + (2*2) = (8*8)
  • a^2 + 4 = 64 (Simplify both sides of the equation)
  • a^2 + 4 - 4 = 64 - 4 (Subtract 4 from both sides)
  • a^2 = 60
  • \sqrt{a^2} = \sqrt{60} (Take square root of both sides
  • a = \sqrt{60}

3. The√(60) is the height of each right triangle, and it's also the height of the isosceles triangle. Therefore, the answer is B) x = √60.

Find the slope rise/run
Sloan [31]

Answer:

m = -1/3

Step-by-step explanation:

Find two points in order to calculate slope:

  • (0, 2)
  • (3, 1)

Slope (m) =

ΔY /ΔX= -1/ 3= -0.33333333333333

  • ( ΔX = 3 – 0 = 3
  • ΔY = 1 – 2 = -1 )

Slope intercept:

y = -0.33333333333333x + 2
