We first split ABC into two right-angled triangles. We name the midpoint of AC, M. AM=1cm, and BM=sqrt(52-32)=4 by Pythagoras. The area of ABC =1/2ACBM=1/264=12. We...
Draw the triangle ABC and fill in the information given i.e. lengths of BA and BC and identify the angle we are looking for i.e angle BAC Looking at the formulas given identify which one...
LCM stands for Lowest Common Multiple, and HCF stands for Highest Common Factor.
The key to telling the difference between these two things is knowing the differen...
The aim here is to turn the fraction so that the denominator does not have a surd.
Given that we know that any surd squared is equal to the number itself, i.e sqrt(2) * sqrt(2) eq...
This is a quadratic equation. There are different ways to solve quadratic equations including factorising them and using the quadratic formula. This is a simple equation so it cn be solved by factorising....
