Note! Every triangle must add up to 360°

1. x =
(×+29°) + (x+19°) + 84° = 360°
x + x + 29° + 19° + 84°= 360°
2x + 48° + 84°= 360°
2x + 132° = 360°
2x = 228°
x = 114°

m(angle)A =
(x+29°)
(114°+29°)=143°

m(angle)B=
(x+19°)
(114°+19°)=133°

3. is a bit different

(3x+6)° = (8x+3)°+130°
-5x+6° = 3° + 130°
-5x = 133° - 6°
-5x = 127°
x = -25.4°

m(angle)A=
(3x+6)°
3×(-25.4)+6= -70.2°

m(angle)DBE=
(8x+3)°=
8(-25.4)+3= -200.2°

I only did 1. and 3. for examples now, but if you need help with anymore just ask!

To the nearest whole percent, what is the probability that a randomly chosen member of the JV swim team does not wear glasses an

Yuri [45]

Answer: 14%

Step-by-step explanation:

Complete question is provided in the attachment below:

Probability that members of the junior varsity swim team wear glasses = 55%=0.55

Given: P(wear glasses) = 0.55

P(not wear glasses) = 1-0.55 = 0.45

P(member in 10th grade | not wear glasses) = 30%

Using conditional probability formula:

$P(B|A)=\dfrac{P(A\text{ and } B)}{P(A)}$

$\Rightarrow\ 0.30=\dfrac{P(\text{not wear glasses and in 10th grade})}{0.45}\\\\\Rightarrow\ P(\text{not wear glasses and in 10th grade})=0.45\times0.30\\\\0.135=13.5\%\approx14\%$

Hence, the probability that a randomly chosen member of the JV swim team does not wear glasses and is in the 10th grade = 14%.

So, the correct option is "14%".
