Find the area of the isosceles triangle with legs 12 and base 17. Simplify all radicals

Andru [333]

Answer:

$Area= \frac{17 \sqrt{865} }{4} \: {units}^{2}$

Step-by-step explanation:

From Pythagoras theorem,

${h}^{2} = {12}^{2} + { (\frac{17}{2} )}^{2}$

${h}^{2} = \frac{865}{4}$

$h = \frac{ \sqrt{865} }{2}$

The area of the isosceles triangle is

$Area= \frac{1}{2} bh$

$Area= \frac{1}{2} \times 17 \times \frac{ \sqrt{865} }{2} = \frac{17 \sqrt{865} }{4}$

A. What are the coordinates of the vertices of the triangle below?

Viktor [21]

Answer:

Solution given:

A.coordinate are

A(-2,3)

B(0,-3)

C(4,5)

B.Each length are :

we have

length $\sqrt{(x2-x1)²+(y2-y1)²}$

now

AB: $\sqrt{(-2-0)²+(3+3)²}$ = $2\sqrt{10}$ units

BC: $\sqrt{(0-4)²+(-3-5)²}$ = $4\sqrt{5}$ units

AC: $\sqrt{(-2-4)²+(3-5)²}$ = $2\sqrt{10}$ units

C. the figure:

By using Pythagoras law

base[b]=AB=perpendicular [p]=AC

hypotenuse [h]=BC

we have

h²=p²+b²

substituting value

( $4\sqrt{5}$ )²=2p²

16*5=2*( $2\sqrt{10}$ )²

80=2*4*10

80=80

SO IT IS RIGHT ANGLED ISOSCELES TRIANGLE.
