37.59
Just multiple .3 x 125.30
132 degrees
You’d do 180 - 48 as it’s the smallest angle and all triangle angles are 180 degrees
In the second one I'm pretty sure you just measure the length of the points.
Answer:
As law of sin:
CD/sinE = DE/sinC
Then
12/sin83 = 5/sinC
Then
sinC = 5*sin83/12 = 0.413
Then
C = arcsin(0.413) = ~24.4 deg
Then
D = 180-C-E = 180-83-24.4 = ~72.6
Hope this help, bro!
