Exam Style Question
Worked solutions to typical exam type questions that you can reveal gradually
Question id: 261. This question is similar to one that appeared in a GCSE Higher paper (specimen) for 2017. The use of a calculator is allowed.
The diagram shows an isosceles triangle (not drawn to scale).
Angle ABC = angle ACB, AB = \(3x+8\) and AC = \(5x-7\).
Use an algebraic method to find the value of \(x\).
The worked solutions to these exam-style questions are only available to those who have a Transum Subscription.
Subscribers can drag down the panel to reveal the solution line by line. This is a very helpful strategy for the student who does not know how to do the question but given a clue, a peep at the beginnings of a method, they may be able to make progress themselves.
This could be a great resource for a teacher using a projector or for a parent helping their child work through the solution to this question. The worked solutions also contain screen shots (where needed) of the step by step calculator procedures.
A subscription also opens up the answers to all of the other online exercises, puzzles and lesson starters on Transum Mathematics and provides an ad-free browsing experience.
