4. Method 1 Show How to find the answer MAIN MENU A straight line =180° PSR Paper X° 90° Question 37° Method 1 Step 1 Considering a straight line is equal to 180º Step 2 90° + 37° + X° = 180° Method 2 Step 3 (90° + 37°) + X° = 180° Step 4 X° = 180° – 127° Step 5 X° = 53°

5. Method 2 Show How to find the answer MAIN MENU This indicates 90° Therefore the other side should be 90° too PSR Paper X° Question 37° Method 1 Step 1 Considering a right angle is equal to 90º X° + 37° = 90° Step 2 Method 2 X° = 90° - 37° Step 3 Step 4 X° = 53°
