Find the measure of the exterior angle. The measures of two interior angles are 75 and 50. The exterior angle variable is 's'. Please help me.

125

Step-by-step explanation:

The exterior angle is equal to the sum of the opposite interior angles

50 + 75 = s

125 = s

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.

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
