Answer:
∠ A ≈ 43.1°
Step-by-step explanation:
Using the Sine rule in Δ ABC , that is
= 
, substitute values
= 
( cross- multiply )
29 × sinA = 20 × sin82 ( divide both sides by 29 )
sinA = 
, thus
∠ A = 
( ) ≈ 43.1° ( to 1 dec. place )
Quadrlilateral, trapezoid and isosceles trapezoid
I am assuming you mean as a whole number, since that fraction can't be simplified down. 20 goes into 100 5 times, so we need to multiply 9 x 5. That gives us 45 and 100, or the new fraction 45/100. 45/100 is equal to 0.45
