about 42.8 because 898 divided by 21 gives you 42.76
Answer:
A
Step-by-step explanation:
the y intercept (where x is 0) should be -3 because of y<3x-3
a) {4,5,6,7,8,9,10}
b) {1,2,3,4,5}
c) {4,5,6}
AB+BC+AC=180°
8 - 7 + 2x +3x -8= 180°
-7+5x=180°
x=180°+7/5
x=37.4°
again
BC=-7+2*37.4
=67.8°
x = 10
c 25
