To find if it's a right triangle, we use the Pythagorean Theorem of a² + b² = c² where a and b are the legs of the triangle (the shorter measurements) and c is the hypotenuse (the biggest measurement).

28² + 34² = 43²
784 + 1156 = 1849
1940 ≠ 1849

No. This is not a right triangle. The sum of the squares of the shorter measurements (AKA the legs) do not equal the square of the biggest measurement.

Find the diameter of circle Z if the center has coordinates (0, 2) and

Angelina_Jolie [31]

Answer:

Diameter of the circle = 2√13

Step-by-step explanation:

The radius is calculated by using the formula for calculating the distance between the two points as shown;

R = √(y2-y1)²+(x2-x1)²

Given the coordinates (0, 2) and (3,4)

R = √4-2)²+(3-0)²

R = √2²+3²

R = √4+9

R = √13

Diameter = 2R

Diameter of the circle = 2√13
