The sum of interior angles of a triangle is 180 degrees. If we’re trying to find the triangles last angle on the right, we will subtract 180-60-50 which equals 70. The angle missing on the right side is 70 degrees. There are opposite angles in this shape so the other angle beside a would also be 70 degrees. Now we only have a left and you do the same thing with the sum of interior angles with that triangle. So you do 180-70-65 and you’re left with 45. Therefore, a is 45 degrees.
Answer:
14π yards^2, or 43.98^2 yards rounded to 2dp
Step-by-step explanation:
circumference = diameter x π
Put each variable's value in parentheses:
P = 2(2.5) + 2(3 2/5)
Solve and get P = 5 + 6 4/5 which as 11 4/5.
The mixed number answer is 11 4/5
