210 (idk maybe since I think this is multiplication)
Answer:
Do (8, -9) times 5 for both numbers
Step-by-step explanation:
Answer:
My best guess would be B and C since those are the only numbers that aren't multiples of 5, and all the values of a(n) are.
Answer: x>-4
Step-by-step explanation:
Answer:
A = 73.33
B = 53.33
C = 53.33
Step-by-step explanation:
Mathematically, adding the 3 angles would equal 180
Thus;
A + B + C = 180 •••••(i)
Since B and C are congruent, that means they are equal ( we are looking at isosceles triangle)
B = C •••••••••(ii)
Lastly;
B = A -20 ••••••••(iii)
Make a substitution in equation 1;
A + A -20 + A -20 = 180
Since B = C ; C also is A-20
3A -40 = 180
3A = 220
A = 220/3 = 73.33
B = C = A -20 = 73.33 -20 = 53.33
