Answer:
A=49 degrees
a= 41 degrees
b=90 degrees
Step-by-step explanation:
its asking for the degrees?
Because you need to have the same denominators to subtract fractions, you need to find the LCM of 15 and 9. The LCM of 15 and 9 is 45. Because 15 goes into 45 3 times, you multiply 2* 3 to find the numerator. Because 9 goes into 45 5 times, you multiply 5*5 to find the numerator. The new equation is 25/45 - 6/45. The answer is 19/45, which cannot be simplified any further.
Answer: Width of canvas = 9 inches
Area left for painting after painting the border = 70 square inches.
