Multiply the triangles then divide to find the missing number
Total length of the wire = 2*13 + 2*5 = 26 + 10 = 36 in.
so length of each side of the triangle would be 36/3 = 12 ins.
Answer:
D
Step-by-step explanation:
The 30-60-90 triangle has the shortest leg as x.
If there is no x you have to use the 2x or 
Answer:
x = 10 units
Step-by-step explanation:
16 is to 40 as x+2 is to 3x
16/40 = (x+2) / 3x
48x = 40x + 80
8x = 80
x = 10
Answer:
the right triangles are B,C,D
