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°

-1, -2, -3, -4, -6

step-by-step explanation:

6(h+1)/2=a

a=area

step-by-step explanation:

its the same thing as a square or rectangle but after multiplying two sides you need to divide it by two.
