Answer:
Step-by-step explanation:
Area of a triangle = 1/2(base)(height)
108 = 1/2(18)(height)
108 = (9)(height)
divide both sides by nine
The height of the triangle is 12 units
Option A:
m∠B = 28°
Solution:
Given ABC is a triangle on the circle.
m∠A = 62°
<em>The angle subtended by a diameter or a semicircle on any point of circle is 90°.</em>
AB is a diameter and C is the angle subtended on a diameter.
Therefore, m∠C = 90°.
Triangle sum property:
<em>Sum of the angles of the triangle = 180°</em>
m∠A + m∠B + m∠C = 180°
62° + m∠B + 90° = 180°
m∠B + 152° = 180°
m∠B = 180° – 152°
m∠B = 28°
The measure of angle B is 28°.
Hence Option A is the correct answer.
Answer:
the inverse operation for addition is subtraction
Answer:
It is the number of ways you can arrange the letters AAABBBCCCF, indicating that three players are on team A, three on team B, and three on team C, with one the field judge F.
Each different arrangement represents one of the ways you can form three teams of 3 with a field judge.
That number of arrangments, and therefore the number of ways to divide the players as required, is
