According to pythagorean theorem, for this to be a right triangle, the sum of square of the length of the two legs must equal square of the length of the hypotenuse (longest side).

So $(\sqrt{34} )^{2}$ should equal $(\sqrt{18} )^{2}+(\sqrt{18} )^{2}$

We also know that $(\sqrt{a} )^{2}=(\sqrt{a})(\sqrt{a})=a$

Hence, $(\sqrt{18} )^{2}+(\sqrt{18} )^{2}=18+18=36$ , and

$(\sqrt{34} )^{2}=34$

They ARE NOT EQUAL, so the triangle is NOT a right triangle.

Which equation correctly shows how to determine the distance between the points (9,-2) and (6.3) on a coordinate grid?

Nastasia [14]

Answer:

d = $\sqrt{(6 - 9)^{2}+ (3 - (-2))^{2} }$

Step-by-step explanation:

The distance formula is d= $\sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2} }$ .

6 is $x_{2}$ , 9 is $x_{1}$ , 3 is y $_{2}$ , and -2 is y $_{1}$ .

When you plug these into the formula, you get d = $\sqrt{(6 - 9)^{2}+ (3 - (-2))^{2} }$

Please help me with this. Please!

Answer:

214

Step-by-step explanation:

A circle is 360 degrees

Arc EF is 146 degrees

EF + EDF = full circle

146 + EDF = 360

Subtract 146 from each side

146-146 +EDF = 360-146

EDF =214
