Solve the triangle. A = 48°, a = 32, b = 27
astraxan [27]

Answer:

C) B = 38.8°, C = 93.2°, c ≈ 43

Step-by-step explanation:

For triangle: a / sin A = b / sin B = c / sinC

32 / sin 48° = 32 / 0.743

32 / 0.743 = 27 / Sin B           sin B = 0.627

<u>B = 38.8°</u>

C = 180 - 48 - 38.8 = 93.2°     sin C = sin 93.2° = 0.998

32 / 0.743 =  c / 0.998 = 42.98     (<u>≈ 43</u>)

Find the length of the missing side of the right triangle. 19 a 15.2​
diamong [38]

The length of the missing side of the triangle is 129.96

<h3>Right angle triangle</h3>

Right angle triangle are triangle that has one of its sides as 90 degrees. The sides can be found using Pythagoras theorem. Therefore,

c² = a² + b²

where

c = hypotenuse

a and b are the other legs.

Therefore,

19² - 15.2² = a²

a = 361 - 231.04

a = 129.96
