A triangle is 180°, so the 3 angles should add up to 180°.
To find m∠R, you can do this:
m∠S + m∠R + m∠T = 180°
56° + m∠R + 30° = 180°
m∠R + 86° = 180° Subtract 56 and 30 on both sides
m∠R = 94°

Answer:
Your answer should be $29.40
Step-by-step explanation:
If you divide 21 by 5 you get 4.2, so each book costs $4.20.
4.2 x 7 = 29.4
Therefore, your total cost for 7 books will be $29.40
