Solve for x. 6/10= 18/x x=30
Answer:
4 5/12
Step-by-step explanation:
4 3/4 = 19/4
19/4 = 57/12
1/3 = 4/12
57/12 - 4/12 = 53/12 = 4 5/12
The angles in a triangle add up to 180, so its
5x+2+6x-10+4x+8=100, then you combine it, so its
15x=180, then divide 180 by 15, and you get 12.
Then insert that into each equation.
4(12)+8= 56
5(12)+2= 62
6(12)-10= 62
They all add up to 180 and two of the angles have the same measure, which makes it an isosceles triangle.
answer:
Contd.
Explanation:
We will use the following well-known
Result : The eqn. of a line l passing through the pt. of
intersection of the lines l1:a1+b1+c1=0andl2:a2x+b2y+c2=0 is of
the form
Result :
It's an equilateral triangle so each angle = 60°
2x-4=60
2x=64
x=32
