C or d i think is the correct answer
Answer:
48 °
Step-by-step explanation:
The following data were obtained from the question:
Adjacent = 12 cm
Hypothenus = 18 cm
Angle R =?
We can obtain angle R by using cosine ratio. This can be obtained as follow:
Cos R = Adjacent / Hypothenus
Cos R = 12 / 18
Cos R = 0.6667
Take the inverse of Cos
R = Cos¯¹ 0.6667
R = 48 °
Thus, <QRP = 48 °
Is there anything else to this problem?
Answer:
550
Step-by-step explanation:
Of means multiply and is means equals
900% * b = 4950
Changing to decimal form
9 b = 4950
Divide each side by 9
9b/9 = 4950/9
b =550
