245-132=x
since riley has 132 out of 245, you would subtract her number from the original number and get sierra's number of minutes which is x
Congruent sides have congruent angles so
w=70
Triangle angles =180 so
70+70+x=180
140+x=180
-140 both sides
x=40
supplimentary angles (angles that make up a line) =180 so
w+y=180
70+y=180
-70 both sides
y=110
triangle angles =180 so
110+25+z= 180
135+z=180
-135 both sides
z=45
w=70
x=40
y=110
z=45
