Answer:
A)60°
Step-by-step explanation:
a straight line is 180° then
if a line bisect it in to a half it become 90°
then
the exterior angle of a triangle is equal to the sum of two interior angles
this means 150°-90°=60°
What are you specifially looking for? simplified it would be 10 and as a fraction 10 over 1
I'm just estimating here,
5/48,3/16,0.5,0.75
