Answer:
-3 degrees
Step-by-step explanation:
7 - 10 = -3
the legenth is (8,2) .
2,75in
4,25in
33in²
shorter base is 2,75in
larger base is 4,25in
S=11+10,5+9+2,5=33in²
450/30
15
15/3x =5
x= 5
5+2y= 315
5-5+2y =315-5
2y = 310
2y/2 = 310/2
y=155
450/45
10
2x+4y=450
2×5=10
10+(4×155)
=620/155
=4
10/5=2
440
55x8. 8x5=40 carry the 4. 8x5=40+4=44 so it is 440
