I really need help find x in this triangle

Mathematics
1 answer:
arsen [322]3 years ago
5 0

Answer:

x = 5

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles and equate to 180

72 + 6x + 2 + 17x - 9 = 180

23x + 65 = 180 ( subtract 65 from both sides )

23x = 115 ( divide both sides by 23 )

x = 5

X-2y=4. -3x+5y=-3. solving linear systems using multiplication and addition show your work
mote1985 [20]
-3x+5y=-3
3x -6y= 12
Multiplied the first equation by 3 so the x's will cancel.
Adding the two equations we get
-y=9
y=-9
Now plug y back in to either equation and solve for x. x-2(-9)=4
x+18=4
x=-14
(-14,-9)
