find the value of each missing variable.

x = degrees

y = degrees

z = degrees

∠x = 110°

∠y = 102°

∠z = 82°

Step-by-step explanation:

x = 180 - 70 = 110

∠x = 110°

y = 180 - 78 = 102

∠y = 102°

z = 360 - (78 + 90 + 110) = 82

∠z = 82°

Step-by-step explanation:

X + 70° = 180° {angle on a straight line is equal to 180°)

X = 180 - 70

X = 110°

Y + 78° = 180°{angle on a straight line is equal 180°}

Y = 180 - 78

Y = 102°

Z + 78° + 70° + 90° = 360°

Z = 360 - 90 - 70 - 78

Z = 122°

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.

mean, 40.6
