Question

In a? triangle, the measure of the first angle is three timesthree times the measure of the second angle. the measure of the third angle is 35 degrees35° lessless than the measure of the second angle. what is the measure of each? angle?

Answer 1

F = first angle
s = second angle
t = third angle

a) f = 3 * s
b) t = s -35
c) f + s + t = 180

c) 3*s + s + (s-35) = 180
5s = 215

second angle = 43 degrees
first angle = 43*3 = 129 degrees
third angle = (43-35) = 8 degrees
