explain how to find the measure of x without finding of its supplement first.

x = 86°

Step-by-step explanation:

The external angle of a triangle is equal to the 2 opposite interior angles.

∠VUC = x is an exterior angle of the triangle and

46° and 40° are the 2 opposite interior angles, hence

x = 46° + 40° = 86°

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
