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

Question

anonymous · Answer

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

anonymous · Answer

i am not sure how to write an equation

anonymous · Answer

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

thanks i got them

"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.
