Sum of interior angles of a triangle is 180
90+51.1=141.1
180-141.1=38.9
Answer:

Step-by-step explanation:
→ Find the total number of people
5 + 14 + 1 + 3 + 15 = 38
→ Find the number of blue
3
Answer:
50
Step-by-step explanation:
because 89-49=49 49 rouded to the nearest ten is 50

then we add 7 and 5 and divide that by 2, which gives you
6 (x-coordinate)
and add 10 and -8 and divide that by 2, which gives you
1 (y-coordinate)the answer is (6, 1)justification
so midpoint is basically the middle point of 2 points
that's why we have to add the two x coordinates first then divide it by 2
or add the two y coordinates then divide it by 2
First, find the area of the circle
pie*radius to the power of 2(radius*raduis)
(11*11=121) 121*3.14=379.94
take your answer and divide it by 4 we would divide it by 2 if we had a semicircle but since we have a 3/4 circle we divide by 4 and then times the Quotient by 3
379.94/4=94.985
94.985*3=284.955
Round ur answer to the nearest tenth so it equals 284.96
