M∠NQS = m∠BQS - m∠BQN = 78 - 48 = 30°
Answer:
<h2>x=(y-105)/7</h2>
Step-by-step explanation:
Given that the total time taken to practice is given by the expression as
y=7(15+x)
Simplifying the expression we have
y=105+7x
Solving for x (that is making x subject of formula we have)
7x=y-105
Divide both sides by 7 we have
x=(y-105)/7
Therefore the expression is
x=(y-105)/7
Divide both sides by cos[x]
<span>You get 1 = Tan[x] </span>
<span>Tan[x] = 1 where x = 45 degrees {+ integer multiples of 180 degrees due to periodicity of tan} </span>
<span>x = 45 + 180*k OR Pi/4 + kPi, for k any integer</span>
