A right-angled triangle has shorter side lengths exactly c^2-b^2 and 2bc units respectively, where b and c are positive real num
yKpoI14uk [10]

Answer: hypotenuse = c^{2} + b^{2}

Step-by-step explanation: Pythagorean theorem states that square of hypotenuse (h) equals the sum of squares of each side (s_{1},s_{2}) of the right triangle, .i.e.:

h^{2} = s_{1}^{2} + s_{2}^{2}

In this question:

s_{1} = c^{2}-b^{2}

s_{2} = 2bc

Substituing and taking square root to find hypotenuse:

h=\sqrt{(c^{2}-b^{2})^{2}+(2bc)^{2}}

Calculating:

h=\sqrt{c^{4}+b^{4}-2b^{2}c^{2}+(4b^{2}c^{2})}

h=\sqrt{c^{4}+b^{4}+2b^{2}c^{2}}

c^{4}+b^{4}+2b^{2}c^{2} = (c^{2}+b^{2})^{2}, then:

h=\sqrt{(c^{2}+b^{2})^{2}}

h=(c^{2}+b^{2})

Hypotenuse for the right-angled triangle is h=(c^{2}+b^{2}) units

Find X and BDL. please Help :(​
tatiyna

Answer:

Step-by-step explanation:

BD=BL(given)

so ∠BLD=∠BDL=3x

90+∠GBD+30=180

∠GBD=180-120=60°

Also ∠GBD=∠BLD (given)

so ∠BDL=60°

3x=60

x=20°

Find the volume of the figure below.
kiruha [24]

Hello!

To find the volume of a cylinder, use the formula: V = πr²h.

In the formula, r is the radius, and h is height of the figure.

In the given figure, the height of the cylinder is 8 feet and the radius is 5 feet. With those values, we can find the volume of the given figure.

V = π(5)²(8)

V = π(25)(8)

V = 200π, 628.32 (multiplied by π), 628 (multiplied by 3.14)

Therefore, the volume of this cylinder is 628.32 feet cubed.
