A right-angled triangle has side lengths of 8.65cm and 10.15cm. What is the length of its hypotenuse?

Step 1: Draw a labelled diagram of the triangle, marking the side lengths. Step 2: Recall Pythagoras’ theorem equation ‘c2=a2+b2’ Step 3: Substitute the values of a and b into the equation. c2=8.652+10.152 Step 4: Solve the equation. c2=117.845 Step 5: Find c by square-rooting both sides of the equation. c=13.3358…cm

Solve 7x=4(x-8)


Rearrange the equation y = 3(x+1)/4, making x the subject.


Solve the equation ((2x+3)/(x-4))-((2x-8)/(2x+1)) = 1 to 2 decimal places.


Given the equations: x + 3y = 1 and 2x - y = -5, solve for x and y.
