Question

Solve. Please show all of your work.
The second angle of a triangle is 4 times as large as the first. The third angle is more than the sum of the other two angles. Find the measure of all three angles.

Answer 1

x+4x+y = 180

Answer 2

hmm i think it's trial and error now..
x = 10
y = 40
x+y = 50
third angle z is probably 130

Answer 3

i mean there are many options for this.

Answer 4

it just said greater than, unless u wrote the question wrong.

Answer 5

sorry!!! the question is:

Solve. Please show all of your work.
The second angle of a triangle is 4 times as large as the first. The third angle is 80 degrees more than the sum of the other two angles. Find the measure of all three angles.

Answer 6

x+4x+(x+4x+80) = 180
5x + 5x + 80 = 180
10x = 100
x = 10
y = 40
z = 130
hmm i did get it right by guesswork.

Answer 7

yes you did!!! cool :)

Answer 8

f + s + t = 180
f + 4f + (5f + 80) = 180
10f = 180 - 80
-->f = 100/ 10 = 10
-> s = 4 * 10 = 40
=> t = 5* 10 + 80 = 130

Pls double check your post ALWAYS!
