ABC has the points A(1,7) B(-2,2) and C(4,2) as it’s vertices

tekilochka [14]

<u>Part 1</u>

Using the distance formula,

$AB=\sqrt{(-2-1)^{2}+(2-7)^{2}}=\sqrt{34}\\\\BC=\sqrt{(-2-4)^{2}+(2-2)^{2}}=6\\\\AC=\sqrt{(1-4)^{2}+(7-2)^{2}}=\sqrt{34}$

So, the measure of the longest side is 6 units.

<u>Part 2</u>

Triangle ABD will have vertices A(1,7), B(-2, 2), and D(1,2).

We already know that $AB=\sqrt{34}$

Using the distance formula,

$AD=\sqrt{(1-1)^{2}+(7-2)^{2}}=5\\\\BD=\sqrt{(-2-1)^{2}+(2-2)^{2}}=3$

So, ABD is a scalene triangle.

<u>Part 3</u>

From part 2, we know that the length of side AD is 5 units.

Study the triangle what can you conclude about the angle measures

lyudmila [28]

If 30 60 90 right triangle then ratio of short leg : long leg : hypotenuse = a : a√3 : 2a

in this case

short leg = 4
long leg = 4√3 (short leg times √3)
and
hypotenuse = 8 (twice of short leg)

so answer is A.
The angle measures are 30, 60 and 90
