Answer: the coordinates For the purple triangle A= -4,5 B= -2,1 C=-5,2

Step-by-step explanation: To the purple triangle are A( X= -4 and Y= 5 so -4,5 for a). B(X= -2.5 and Y=1 so -2.5,1 for b ). C(X=-5 and Y= 2 so -5,2 for c).

The string of a kite is 120 metres long and it makes an angle of 60 degree

Afina-wow [57]

Answer:

103.92 m

Step-by-step explanation:

The kite is making right angle with the ground and its string is acting as hypotenuse of right triangle.

Let the height of the kite from the ground be h meters.

Therefore, by trigonometrical ratio:

$\sin \theta \: = \frac{height \: of \: the \: kite}{length \: of \: the \: string} \\ \\ \sin 60 \degree \: = \frac{h}{120} \\ \\ \frac{ \sqrt{3} }{2} = \frac{h}{120} \\ \\ h = \frac{ \sqrt{3} }{2} \times 120 \\ \\ h = \sqrt{3} \times 60 \\ \\ h = 1.732 \times 60 \\ \\ h = 103.92 \: m \\$

Thus, the height of the kite from the ground is 103.92 meters.

Isabella uses the equation V = one-third (12) squared (9) pi to find the volume of the cone below.

lyudmila [28]

Isabella’s error is Isabella should have divided the product of 12π and 9 by 3 to get V = 12π(9)/3 option fourth is correct.

It is defined as a three-dimensional shape in which the base is a circular shape and the diameter of the circle decreases as we move from the circular base to the vertex.

$\rm V=\pi r^2\dfrac{h}{3}$

Isabella equation:

$\rm V = \dfrac{1}{3}(12)^2(9)\pi$

The area of the base = 12π square cm

$\rm V = \dfrac{12\pi (9 )}{3}$

Thus, Isabella’s error is Isabella should have divided the product of 12π and 9 by 3 to get V = 12π(9)/3 option fourth is correct.
