Hey mate what's your skype, I can help you with more of these - just finished year 12 with flying colours completing calculus and applicable maths (I'm not sure what Americans would refer to those courses as, but they're the 2 highest math courses an Australia highschool student can do)

 

 

Q21) x = -7         A = 44º

 

Q22) x = -7         A = 30º

 

The interior of both those triangles must add up to 180º

 

just found out how to do that thanks man

now i need help on 23

 

 

23 is the same, interior angle must add to 180 so (3x-6) + 60 + (8x+4) = 180

-> 11x+58=180

-> 11x=122

-> x = 11

 

and as angle A = 3x-6. A=27 degrees

That shit is gay ur not even gonna use it there just cramming all that crap into your brain.

In the exercise 13), from median of triangle we know that

|ET| = 2*|TM|

 

Where |TM| = |EM| - |ET| = 5X - (3X+2)

so |TM| = 5x - 3x - 2 = 2x - 2

 

3x - 2 = 2*(2x-2)

 

3x - 2 = 4x - 4

-x = -6

x = 6

 

How does help coming from the person you publicly insulted feels like?

I wonder, really. Even if you have some java knowledge, doesn't mean you have to act like jackass, and until yesterday, I respected you, until you've shown me what kind of a child you are.
