The first step is to write x=0.0755... For this question the number that is recurring here is the 555…so what we want is to get two equations with the same recurring part after the decimal point. By multi...

Probability is how likely something is to happen, and we sometimes here it called chance. So, the probability of something happening means how likely it is to happen. It can be expressed in two main ways:...

(In terms of formatting, we'll use little x "x" to mean the algebraic variable, and big x "X" to mean multiply). When we see two sets of brackets written next to each other, such as (....

If I were to get the job, I would get a writing board to help explain this. But to approach this question, it's a good idea to draw the graph. You know that the tangent line is a straight line and as the ...

Using the sine rule it's possible to find the length opposite to the 72° angle. Therefore: 5/(sin63)=x/(sin72) x=5sin(72)/sin(63)=5.34 At this point, the third angle is needed. Since a triangle has a tota...
