Answer:
40°
Step-by-step explanation:
e = 20°
d = 20°
c = 140°
b = 40°
6(x+5)² + 5(x+5)-4 = 0
(x+5)(x+5) = x(x+5)+5(x+5) = x² + 5x + 5x + 25 = x² + 10x + 25
6(x²+10x+25) + 5(x+5) - 4 = 0
6x² + 60x + 150 + 5x + 25 - 4 = 0
6x² + 60x + 5x + 150 + 25 - 4 = 0
6x² + 65x + 171 = 0

Answer:
Step-by-step explanation:
Given :
Juan rolled a six-sided number cube 18 times.
The number two occurred four times.
To Find: Juan claimed the experimental probability of rolling a two was approximately 1/9. Why is Juan’s experimental probability incorrect?
Solution:
Total events = number of times cube rolled = 18
Favorable events = The number two occurred four times. = 4
So, Experimental probability = 
= 
=
Thus the experimental probability of rolling a two was
So, Juan’s experimental probability was incorrect.
Answer:
answer is 52 cm
Step-by-step explanation:
BA = 17, BF = 6, and CG = 9
triangle sides BF and BH are congruent because they are tangent lines along the same curve
BH is equal to 6 since BF is equal to 6
this applies to CG and CF and AG and AH
CG is equal to 9
so CF is equal to 9
now we add 6 + 9 for the measurement of side CB
CB = 15
now we do the same for the other two sides
we already know BA = 17 so we subtract it from BH = 6 to find the measurement of AH
AH is equal to 11 and is tangent across the same curve as AG
AG = 11
now we add AG to CG
11 + 9 = 20
now we know all the side lengths
CB + BA + AC = Perimeter
15 + 17 + 20 = 52
Perimeter of triangle BCA = 52
I don't know why I went through all the trouble if I know no one is going to see this :'(. I just thought the other guy gave the wrong reasons
