Step-by-step explanation:
since we are required to find side |BC| and the value of side |AB| is given as 6.3 cm
hence we find the cosine of the given angle...
cos71 = adjacent ÷ hypotenuse
cos71 = |AB| ÷ |BC|
cos 71 = 6.3 ÷ |BC|
|BC| = 6.3 ÷ 0.325
|BC| = 19.4 cm
Answer:
85 minutes.
Step-by-step explanation:
T = Tuesday
M = Monday
T = M - 15, 70 = M - 15, M = 85 minutes.
Since she worked out 15 minutes less than monday on tuesday, you add 15 to 70, since thats what she did on tuesday.
I think they are called sides.
Reflection of point (x ,y) about x axis is given by (x,-y) and about y axis is given by (-x,y) .treat the line as plane mirror about which you have to find out point reflection .thus Q is (5 ,-6) and R is(-5,6)..
