Recall: SOHCAHTOA
Sin M = Opp/Hyp
Reference angle = M
Opp = 3√/21
Hyp = 15
Sin M = (3-√21)/15
Sin M = √21/5
Cos M = Adj/Hyp
Reference angle = M
Adj = 6
Hyp = 15
Cos M = 6/15
Cos M = 2/5
Tan M = Opp/Adj
Reference angle = M
Opp = 3√21
Adj = 6
Tan M = (3√21)/6
Tan M = √21/2
:Therefore: Sin M = √21/5
Cos M = 2/5
Tan M = √21/2
Subtract the expression on the right of the equal sign. Collect terms. (Write the exponent properly.)

Answer:
787.5 cm^2.
Step-by-step explanation:
This consists of a parallelogram and a trapezium.
Area of parallelogram = 23 * 14 cm^2.
Area of the trapezium = 1/2 * (19) * ( 15 + 34)
Total area = 23 * 14 + 1/2 * 19 * 49
= 787.5 cm^2.
Answer:
5cm
