Answer:

x=17

Step-by-step explanation:

well the triangles are congruent so that equation has to equal 61, so set it equal to 61, once you do that subtract 10 with 61 giving you 51, then divide 3 with 51 and you get 17

$3x + 10 = 61 \\ 3x = 51 \\ x = 17$

What is the maximum number of intersection points between two triangles?

Andrei [34K]

Answer: six ( 6 ).

Step-by-step explanation:

If Each of a side can, consisting of a shape with only convex angles (which are known to be triangles and squares if we follow definitions ). make at most two intersections. Then, the triangle has the fewest sides, so its upper boundary is set for number of intersections at 2*3, or 6. So basically the maximum number available is 6.
