Answer:
X=3 (hope this helps)
Step-by-step explanation:
So what you want to see if they are equal (in this case they are) so we have 10 plus 12x and we also have 15x plus 1
10 + 12x = 15x + 1 (solve for x)
-15x + 12x=1 - 10
-3x = -9
x=3
lets see if our answer is correct :)
15 x 3= 45 + 1 = 46
12 x 3 = 36 + 10= 46
Number six is 163 cm because the width which is 5 plus another five because of the another side is 10. 34-10=24=the length added together. 24/2=12=the length. 12+5=17. 1 triangle= 180. 180-17=163. so, the perimeter of triangle ABD is 163 cm.
