Answer:
Q + S = 360 - 55 - 45 = 260
Q = S
=> Q = 260/2 = 130
C is correct
Answer:
171.65
Step-by-step explanation:
A=2AB+(a+b+c)h
AB=s(s﹣a)(s﹣b)(s﹣c)
s=a+b+c
2
Solving forA
A=ah+bh+ch+1
2﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4=5·10+5·10+5·10+1
2·﹣54+2·(5·5)2+2·(5·5)2﹣54+2·(5·5)2﹣54≈171.65064
the roots are -1/2 and -5
the smaller root would be -5 since its further away from the 0
