Question

in a tiriangle abc angle b is 5 times angle a and angle c is 2 degress less tahn 4 times angle a find the size of the angles

Answer 1

all the angles in a triangle add up to 180. write an equation of all angles in terms of angle a and solve

Answer 2

i am not sure how to write an equation

Answer 3

b = 5a
c=4a-2
thus a + 5a+ (4a - 2) = 180
a+5a+4a-2=180
10a-2=180
10a=182
a=18.2
Since we have a, you can find the other angles

Answer 4

thanks i got them

Answer 5

"all the angles in a triangle add up to 180." Its correct only when the triangle is in Euclidian Space. Remember that. Its very important thing.
