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.
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.
The longest side of a triangle is always what the angle with the largest measure?
across from, or opposite to

What is triangle that has angles that measure 30 60 90 degrees?
A right triangle, whose the length measure of the side opposite to the angle of 30 degrees is one half of the length measure of the hypotenuse.
Is the longest distance between two points in a triangle the length of the longest side?
The largest side of a triangle is directly across from the largest angle of that triangle.
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 an example of a obtuse triangle and a scalene triangle?
An obtuse triangle is a triangle whos angle measure is greater than 180. The length of the sides of a scalene triangle are all different.

The longest side of a triangle is always opposite the angle with the measure?
angle with the greatest measure
