If two angles of a triangle are congruent then the sides opposite those angles are congruent by the converse to the Isosceles Triangle Theorem?
Yes, because an isosceles triangle has two equal base angles and two equal sides.
What is the vertex of a isoscles triangle that is 9 degrees more than the base angle?
The isosceles triangle will have a top angle of 66 degrees and two equal base angles of 57 degrees which all add up to 180 degrees.
How tall can the funnel of a tornado get?
The funnel of a tornado always connects to cloud base and typically all the way to the ground (the circulation of a tornado can reach the ground even if the funnel does not). Cloud base height is variable but in a tornado supercell is usually about 3000 feet to a mile above the ground. The circulation of the tornado usually goes a great distance above cloud base and can reach heights of more than 4 miles.
What is a use of trigonometry to find the heights of buildings and trees?
Trigonometry is the study of angles ond lengths. If you know one angle and one side length of a right traingle, you can find all the other values. If you know your distance from a tall object, and the angle made by the base of the tall object, your feet, and the top of the object, you can find the height of the object.
How do you find the area of a right angle?
the equation is 1/2 x base x height or (base x height)/2
