Two of the angles in a triangle measure 55° and 28°. What must be the measure of the third angle? The measure of the third angle is

Work Shown:

Let x be the third angle

For any triangle, the three angles always add to 180 degrees

x+55+28 = 180

x+83 = 180

x = 180-83

x = 97

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !

by definition, an arc subtended by a central angle of some given measure has the same measure. so .
