Premium Right Angled Trigonometry Angles | Maths Codebreaker | Answers Included

PREMIUM RESOURCE - available to purchase; this is not a free download.

Use inverse trigonometric ratios to find acute right-triangle angles.

This Premium paid resource contains one complete A4 pupil worksheet with 21 questions and a matching answer page with workings, plus a product-family guide. Pupils solve the maths, match answers to letters in the code grid and decode the hidden words.

Difficulty: Level 7 of 10 within this range (1 is easiest; 10 is most demanding). These levels are a guide to relative challenge, not GCSE grades.

Three questions from this worksheet:
1. Right triangle: adjacent side 7 cm, opposite side 9 cm. Find angle x in degrees, to 1 decimal place.
2. Right triangle: adjacent side 12 cm, hypotenuse 14 cm. Find angle x in degrees, to 1 decimal place.
3. Right triangle: opposite side 13 cm, hypotenuse 16 cm. Find angle x in degrees, to 1 decimal place.

Use for focused practice, consolidation, homework or a lesson activity after teaching the method. Print the pupil page for learners and retain the answer page for checking. Follow the rounding and unit instructions on the sheet.

This resource belongs to a completed 100-topic Maths Codebreakers range. Halloween codebreaker resources are also available. A mixed-topic revision codebreaker range is coming soon. These other ranges are separate resources and are not included in this download.
