2.37 + 0.35 = 2.72 total spent
5.00 - 2.72 = $2.28 change back
Okay first, use the sin rule (

so

sin^-1 this and you get 47.928....this is angle ADB
and as it is on a straight line, 180 - this angle gets ADC
180 - 47.928.... = 132.07
Answer:
Step-by-step explanation:
35-original drill set price
25% or .25-the additional price
