❒ Required Solution:

We are here to find the three angles with the help of the angle sum property (Sum of the angles of a triangle = 180°). So, using this property we can find all the angles.

❍ According to the question :

$\\ \tt \implies \: 60{}^{ \circ} + 60{}^{ \circ} +(4x - 80) {}^{ \circ} = 180{}^{ \circ} \\ \\ \\ \implies \tt \: 120{}^{ \circ} - 80{}^{ \circ} + 4x = 180{}^{ \circ} \: \: \: \: \: \: \\ \\ \\ \implies \tt 40{}^{ \circ} + 4x = 180{}^{ \circ} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \\ \implies \tt \: 4x = 180{}^{ \circ} - 140{}^{ \circ} \: \: \: \: \: \: \\ \\ \\ \tt \implies \: 4x = 140{}^{ \circ} \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \\ \implies \tt \: x = \frac{140}{4} \: \: \: \: \: \: \: \: \: \: \\ \\ \\ \tt \implies \: { \boxed{ \mathfrak{ \pmb{ \pink{x = 35}}}}} \bigstar \\ \\ \\$

Answer:

x = 35

Step-by-step explanation:

Sum of angles of triangle = 180°

60 + 60 + 4x - 80 = 180
40 + 4x = 180
4x = 140
x = 140/4
x = 35°

Given: △ABC,

Alexxandr [17]

we are given

△ABC

we can use area of triangle formula

$A=\frac{1}{2} AB*BC*sin(B)$

we have

AB=6

BC=10

m∠B=120°

so, we can plug it

$A=\frac{1}{2} 6*10*sin(120)$

$A=\frac{1}{2} *60*\frac{\sqrt{3} }{2}$

$A=15\sqrt{3}$ ..............Answer

Use this attachment to answer 1-3

nignag [31]

Simple,

1.) A vertical angle, is an angle directly across another angle. Thus, <2 and <5 are vertical angles.

2.)This is another pair of vertical angles, thus, m<4 is 53.

3.)Since m<1 is 50

You have the m<4 which is 50. You already have m<3 which is the right angle, 90.

Thus, 90+50=140

You know a line is supposed to be 180 degrees. So take,

180-140=40

Thus, the m<5 is 40.

37% of women consider themselves fans of professional baseball. you randomly select six women and ask each if she considers hers

valina [46]

Answer:

(a) 2.22

(b) 1.3986

Step-by-step explanation:

Let X denote the number of women who consider themselves fans of professional baseball.

The proportion of women who consider themselves fans of professional baseball is, p = 0.37.

A random sample of n = 6 women are selected and each was asked if she considers herself a fan of professional baseball.

Each woman's reply is independent of the others.

The random variable X thus follows a binomial distribution with parameters n = 6 and p = 0.37.

(a)

Compute the mean of the binomial distribution as follows:

$\text{Mean}=np=6\times 0.37=2.22$

(b)

Compute the variance of the binomial distribution as follows:

$\text{Variance}=np(1-p)=6\times 0.37\times (1-0.37)=1.3986$

(c)

Compute the standard deviation of the binomial distribution as follows:

$\text{Standard Deviation}=\sqrt{np(1-p)}=\sqrt{6\times 0.37\times (1-0.37)}=1.183$
