Question #6dd5c

Answer 1

Measure of `Delta ABC` is `color(blue)(61.1822, 70, 85.4595)`

Explanation:

Sum of three angles of a triangle is `180^0`

`/_C = 180 - 45 - 54 = 81^0`

`a / sin A = b / sin B = c / sin C`

`a / sin 45 = 70 / sin 54 = c / sin 81`

`a = (70 * sin 45) / sin 54 = 61.1822`

`c = (70 * sin 81) / sin 54 = 85.4595`
