Answer: y = 90°
Step-by-step explanation:
55.30786941 = sin-1 (148/180) round to 55.3° angle x
34.69213059 = cos-1 (148/180) . round to 34.7° "angle z" at right
34.7 +55.3 = 90
Sum of All angles of the triangle = 180° 180 -90 = 90
If angle x is 55.7 and angle z is 34.7° Angle y must be 90°
Ratio of inscribed arcs = ratio of chord to diameter
If you add all the gumballs together you get a total of 20200 gumballs now you just divide 5252 by the total number of 20200 to get the percent of 26% giving us the answer to what the percent of red there is in this container
(add all the number, divide the total number of reds by the total number of gumballs (5252 divided by 20200) which will give you the percent of red gumballs (26%)
16 bc one side is 5ft so the other must be 3 to have an area of 15. Then 5+5+3+3= 16ft
