So angles on a straight line add up to 180°
And angles in a triangle adds up to 180° try if you can work it out now
If you still don’t understand let me know
We start with:
y=2x-15
y=5x
Now, we have a perfectly set-up variable we can get rid of: <em>y.</em>
But we need to make either the top or bottom equation negative, so for simplicity, let's make the bottom one negative.
y=2x-15
(-y)=(-5x)
Now simplify.
-3x-15=0
Add 3x on both sides.
3x=15
Divide by 3 on both sides.
x=5
135 ; If you are allowed to use a calculator to determine percents you can do 300 × 45% = and it gives you your answer.
Step-by-step explanation:
180°=46° +2x=> 2x=134°=>x=67°
x+y=180°=>y=180° -x=>y= 180°-67°=>y=113°
