help me solve this pls

where r u getting 8 from?

7x+4 and 3x+6 together give you 90 degrees

7x+4+3x+6=90
10x+10=90
10x=80
x=8

7(8)+4=60
3(8)+6=30

Lol, everybody is solving for x. That is only one part of the solution. Once you find x, you must substitute it within the equation. So basically you would replace x with 8. If you do this, then you will find that 7(8)+4=60, and that 3(8)+6=30.

You're gonna be in some deep shit.

7x+4 + 3x+6= 90

Combine like terms.

7x + 3x + 4+6= 90

10x+10=90

Subtract 10 from each side.

10x= 80
Divide each side by 10.
X=8

Since the value of x is 8, substitute x in each of the inequalities for 8.

really? helping people on here to make your homework...

Do your own homework, kid.

That problem is not hard....at all.

Open up your textbook and review the section. NarutoBase won't be here to "help" you when your exam comes up. The word help used very loosely...

He has attempted the question already. It's not like he is coming here and asking people to cheat for him. As for consulting a textbook, let me know of any which have chapters dedicated to solving for angles which for some reason are expressed as linear systems. This question is meant to test basic algebra and manipulation, something he must already be familiar with to have already attempted it.

Go down so low as to ask for help on a Naruto fan sight.... Kids these days...

What exactly is low about asking for help? At least he cares enough to seek help so he can answer it correctly.


I'm a little unsure of the wording used "find the measure of each angle"? Just looking for the value of each angle in degrees?
(7x + 4) + (3x + 6) = 90
10x = 80
x = 8

7x + 4 = 7*8 + 4 = 60
3x + 6 = 3*8 + 6 = 30

I'm guessing that was the same working you followed. I agree with your answer. Is it possible the test answer is incorrect?

the answer is 60 / 30 . the test is right, it just shows you the correct answer, but when you put your cursor on the correct answer, it shows your incorrect answer.

Okay that makes sense. I am just used to Maple TA which only shows your incorrect answer and assumed it was saying 60 degrees and 30 degrees were incorrect.

Do you fully understand the working behind those answers?

yeah i get it now , thanks

i looked at the book and everything, but the quiz the teacher gives us online is much harder than the book problems.
