1. The problem statement, all variables and given/known data Ok, so this is really basic and i could do it at the snap of a finger liek a year ago but it's completely escaped me. Maths is too much. This is a right angle triangle, with the right angle on angle C. Angles are marked A, B and C. Side CB = Adjacent, Side BA = Hyp and side CA = opposite. A smaller triangle is sat with it's hypotenuse as side CA. It's a right angle triangle with D as the right angle, which sits on a line that travels from C to directly over A. a) Calculate size of angle BAC. Give your answer to 1 DP. b) Calulate length of DA. Give your answer to 3 sf. 2. Relevant equations AB = 22cm AC = 10cm Angle ACB = angle ADC = Angle BAD = 90 3. The attempt at a solution I'm stuck. It's a simple bit of knowledge I've forgotten. Something to do with Sineθ ?
