an isosceles triangle has congruent sides of 20cm. the base is 10cm. find the height of the triangle.

dolphi86 [110]

Answer:

$\large\boxed{A_\triangle=25\sqrt{15}\ cm^2}$

Step-by-step explanation:

Look at the picture.

The formula of an area of a triangle:

$A_\triangle=\dfrac{bh}{2}$

b - base

h - height

We need a length of a height.

Use the Pythagorean theorem:

$leg^2+leg^2=hypotenuse^2$

We have:

$leg=5,\ leg=h,\ hypotenuse=20$

Substitute:

$5^2+h^2=20^2$

$25+h^2=400$ subtract 25 from both sides

$h^2=375\to h=\sqrt{375}\\\\h=\sqrt{(25)(15)}\\\\h=\sqrt{25}\cdot\sqrt{15}\\\\h=5\sqrt{15}\ cm$

Calculate the area:

$A_\triangle=\dfrac{(10)(5\sqrt{15})}{2}=\dfrac{50\sqrt{15}}{2}=25\sqrt{15}\ cm^2$

Step-by-step explanation:

An entire amount is 100% of the amount.

50% is half of 100%, so 50% means the same as half.

Half of 62 is the same as 62/2 = 31

Answer: 31

Find the diagonal of a square whose sides measure 3 square root 2

mrs_skeptik [129]

The Pythagorean theorem can be used to find the length of the diagonal (d) of a square.

d² = (3√2)² + (3√2)² = 18 + 18 = 36

d = √36 = 6

The measure of the diagonal is 6.
