Answer:

96°

Step-by-step explanation:

In a cyclic quadrilateral (one inscribed in a circle), opposite angles are supplementary. That means the angles marked (6m+13)° and (4m+7)° have a total value of 180°:

(6m+13) +(4m+7) = 180

10m +20 = 180 . . . . . . . . collect terms

m +2 = 18 . . . . . . . . . . . . .divide by 10

m = 16 . . . . . . . . . . . . . . . subtract 2

∠M = 6m° = 6·16° . . . . . . . use the value of m in the expression for ∠M

∠M = 96°

They're usually 365 days in each year every 4th year is call a leap year and has one extra day in February how many days are the

Mariana [72]

Answer:

Total number of days in 8 years is 2,922 days.

Step-by-step explanation:

Number of days in a Normal year = 365 days

Number of days in a leap year = 366 days

Also, Leap year comes exactly ONE TIME in every FOUR YEARS.

⇒ In every consecutive 4 years, 1 year is a leap year.

⇒ So, number of leap years in 8 years = 2

Now, 8 Years = 6 Normal years + 2 leap Years

<u>Number of days in 6 normal years</u>

= 6 x ( Number of days in a regular year)

= 6 x (365 days) = 2,190 days

<u>Number of days in 2 leap years</u>

= 2 x ( Number of days in a leap year)

= 2 x (366 days) = 732 days

So, Total number of days in 8 years

= Number of days in 6 regular years + Number of days in 2 leap years

= 2,190 days + 732 days

= 2,922 days

Hence, total number of days in 8 years is 2,922 days.

Answer:

C. 8√3/3

Step-by-step explanation:

It can be useful to remember that the ratio of sides in a 30°-60°-90° triangle are ...

1 : √3 : 2

That is the short leg is 1/√3 times the length of the longer leg.

8(1/√3) = 8(√3/3) . . . . . matches choice C

Pls help me!!!

Olenka [21]

Answer:

Step-by-step explanation:

A box plot is the diagrammatic representation of the five number summary. It includes 5 items:

The minimum.

Q1 = the first quartile or the 25% mark.

The median.

Q3 = the third quartile or the 75% mark.

The maximum.

Rearranging the data in ascending order, it becomes

169, 163, 153, 166, 149, 148, 146, 145, 152, 163

145, 146, 148, 149, 152, 153, 163, 163, 166, 169

Minimum = 145

Maximum = 169

Median = (152 + 153)/2 = 152.5

The median divides the data into two equal halves. The middle of the lower halve is Q1 while the middle of the upper halve is Q3

Q1 = 148

Q3 = 163

The diagram of the box plot is shown in the attached photo

Given f(x)=x-8 find f(1)+10

Ronch [10]

Answer:

Step-by-step explanation:

replace all x variables with 1 and solve that equation ; f(x)=x-8 so.... f(x) = 1-8

there for f(1)=-7

now, add -7 and 10 for your answer:

f(1)+10= 3
