If l is parallel to m in this figure, find x. line l = 3x+50 line m = 2x-20
@BillRosie
Okay, forget about the question and concentration on my questions alright? :)
Okay so first we have that: |dw:1341024318614:dw|
|dw:1341024365551:dw| What can you say about these two angles?
they r congruent?
i think if we sum both of these angles.we get \[(3x+50)(2x-20)=180\]
Sorry, by adding
Wonderful :| All those explanations were gone after yesterday's crash >.> :( but yeah, what I wanted to explain is if angle 2+5=180 Therefore \((3x+50)+(2x−20)=180\) Solve for x and replace x in the respective angles to find their value.
so is 180 the answer??
Yeah!!
No... \( (3x+50)+(2x−20)=180\\5x+30=180\\5x=180-30\\5x=150\\x=150\div5=30\)
The angle (2x−20) would be (2(30)-20)=40 The angle (3x+50) would be (3(30)+50)=140
Oh, yeah @zepp is right.
I've already posted the last step before the answer: ========= Therefore (3x+50)+(2x−20)=180 Solve for x and replace x in the respective angles to find their value. ========= It's quite deceiving that you didn't even read that carefully, you have eyes, use them.
