Answer:
long pieces 126 Short pieces 21
Step-by-step explanation:
18+18+18+18+18+18+18=126

hope this helped <3
<span>the answer
The triangle congruence says triangle ERT is congruent to triangle CTR. </span>
A triangle interior angles add up to 180
so we have 3:4:5
the ratio of the angles
3+4+5=12
therefor 180=12 units
divide by 12
15=1 unit
subsitute
find the smallest unit
3
3 times 15=45
answer is 45 degrees
