Answer:
m∠B = 66.3°
a = 0.0319
b = 0.0726
Step-by-step explanation:
Sum of the interior angles of a triangle = 180°
⇒ m∠A + m∠B + m∠C = 180°
⇒ 23.7 + m∠B + 90 = 180
⇒ m∠B = 180 - 90 - 23.7 = 66.3°
We can use the sine rule to help solve the missing side lengths.
<u>Sine rule</u>
where A, B and C are the angles and a, b and c are the side lengths opposite the angles.
Therefore,

Common
Step-by-step explanation:
Answer:
27
Step-by-step explanation:
(3²)³/3³ =
3 x 3 = 9
9 x 9 x 9 = 729
3 x 3 x 3 = 27
729/27 = 27
He needs to earn ; 77.99-20= 57.99 dollars
so in one week there are 2 weekends; so he earns 6×3×2 = 36 dollars
so no of week = 57.99÷ 36= 1.6 weeks
so weeks are in natural no thus it will take him 2 weeks !!
