WebMar 13, 2024 · To solve, isolate the sine of the unknown angle by multiplying both sides of the equation by the length of angle theta's opposite side. In a calculator, given side a = 5, side b = 7, and angle A = 45 degrees, this is seen as SIN^-1 ( (7*SIN (45))/5). This gives angle B a value of approximately 81.87 degrees. WebWe know, however, that ∠CAE is supplementary to ∠A, since they form a linear pair. We can state that m∠CAE = 180 - m∠A and from ΔCAE that . If we apply a trigonometric fact that sin∠A = sin(180 - m∠A), we can substitute and get: (After multiplying both sides of the first equation by b.) Now, substitution into the general formula for the area of a triangle will …
