Answer:
A. 60°
Step-by-step explanation:
From the diagram, in triangle ABC,
AB=BC=CA=15 units.
This means triangle ABC is an equilateral triangle.
All angles in equilateral triangle are congruent. The sum of all interior angles in triangle is always 180°, so one angle of equilateral triangle is equal to 60°. Thus,
∠A=∠B=∠C=60°
Hope this helps have a nice day
P=18
l=5 cm greater than the width
w=5 less than the length
USE YOUR NUMBER SENSE!!! - just plug in different number below 4 to figure out the width
3=w 3+5=8 8+8=16+6=22 WILL NOT WORK
2=w 2+5=7 7+7=14 14+2+2= 18 WE HAVE A WINNER!!!!
