The logo shown is symmetrical about one of its diagonals. Enter the angle measures in the green triangle, to the nearest degree. (Hint: First find an angle in a blue triangle.) Then, enter the area of the green triangle, without first entering the areas of the blue triangles. Round your area to the nearest tenth.

answer: both chords and diameters have two endpoints on a circle. diameters must intersect the center of a circle.

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
