This is Pythagorus. The formula is a2=b2+c2. The Diagonal side is A, The Horizonal side is B and the Vertical side is C. So we simply sub in 9cm and 8cm for B and C, then solve for A. a2=b2+c2 a2=(9)2+(8)2 a2=81+64 a2=145 a=√ 145 a=12.04 to 2dp

How do you find the side of a triangle?

To find the degree of angle of a side of a triangle, a protractor is needed to measure the angle. Place the '0' on the protractor on the point of the angle and look at the top part to determine degree of angle. To measure the length of a triangle side, a simple ruler can be used to measure the length.


How do you use sine in math?

The sine function is used in trigonometric calculations when attempting to find missing side lengths of a right triangle. The sine of an angle in a triangle is equal to the length of the side opposite of that angle divided by the length of the hypotenuse of the triangle. Using this fact you can calculate the length of the hypotenuse if you know an angle measure and the length of one leg of the triangle. You can also calculate the length of a leg of the triangle if you know an angle measure and the length of the hypotenuse.


In any triangle the shortest side is across from which angle largest angle middle angle an angle smallest angle?

In any triangle, the shortest side is across from the smallest angle. This relationship holds true due to the triangle inequality theorem, which states that the length of a side is directly related to the measure of its opposite angle. Therefore, as the angles increase in size, the lengths of the sides opposite them also increase.


What is the measure of an angle in a right angled triangle found by dividing the length of the side adjacent to the angle by the length of the hypothenuse?

cosine


What is an ambiguous triangle?

The answer may refer to a triangle for which the length of two sides and the measure of an angle - other than the included angle - are known.

What is the length of the hypotenuse of a right triangle whose legs measure 30 in and 72 in?

Using Pythagoras' theorem for a right angle triangle its hypotenuse length is 78 in.


How to measure length of two sides height diagonal of a right angle triangle where all degrees of angle and length of base given?

The answer depends on whether the base is one of the legs of the right angle or the hypotenuse. Also, a triangle cannot have a diagonal.

What is triangle that has angles that measure 30 60 90 degrees?

A triangle with angles that measure 30, 60, and 90 degrees is a special type of right triangle known as a 30-60-90 triangle. In this triangle, the side opposite the 30-degree angle is half the length of the hypotenuse, and the side opposite the 60-degree angle is √3 times the length of the side opposite the 30-degree angle. This relationship is based on the properties of trigonometry and the ratios of the sides in a 30-60-90 triangle.
