measure of angle 1 equals 3x and measure of angle 3 equals (7x-40)...... i don't get this
Is this about a triangle or what?
its about angles
I want to help but i feel as though i don't have all the info i need. Are angle 1 and 3 perpenticular or suppose to be similar or on the inside of a triangle?
they're on the outside
On the outside of what kind of triangle? right triangle or what? If you copy and paste the picture it might help or go more in depth with details please. Is that the entire question? Help me help you hahaha
well i don't have a picture but all it says is to find the value of the vaariable and the angle measures ... they have to add up to 180
Well you only gave me two angles is the other angle assumed to be 90 degrees?
what? its NOT a triangle. they're like intersecting lines
what grade is this?
8th
okay...... give me a sec. i had a question like this a few weeks ago. bjut im in the 6th do it may be hard for me to try and explain
my teacher didn't explain nothin about this that's why i don't get it
i kno what you mean. i think it means multiply the measure of angle two by 3.
scratch that. "angle 1 equals 3x and measure of angle 3 equals (7x-40)."
angle 1- 3•x
angle 3- 7•x-40
use the x in angle 3 and multiply it by 3.
When you first typed it, there was not enough information.
Then in your 7:42 post you stated that they add up to 180°, (they would form a straight line)
Well, that makes it very easy ....
3x + 7x-40 = 180
10x = 220
x = 22
so one angle is 3x = 3(22) = 66°
the other is 7x-40 = 7(22)-40 = 114°
(notice they add up to 180°)
