Answer:

1. x = 21

2. m∡ABC = 51°

Step-by-step explanation:

First problem, solve for x

the sum of inside angles of a triangle is 180

also the supplementary angle for L = 180 - 100 is 80°

now you can add all angles

80 + 2x - 11 + 2x + 27 = 180

4x + 96 = 180

4x = 84

x = 21

Second problem, solve for m∡ABC

the sum of inside angles of a triangle is 180

also the supplementary angle for C = 180 - 148 is 32°

now you can add all angles

31 + 2x - 15 + x - 5 = 180

3x + 12 = 180

3x = 168

x= 56,

now solve for m∡ABC = (x - 5)° = (56 - 5)° = 51°

Answer:

Interquartile range, median, and range

Step-by-step explanation:

The five-number summary that a box plot displays are minimum value, maximum value, median, first quartile, and third quartile.

This means that interquartile range = Q3 - Q1 can be determined from the box plot.

Median cam be gotten, and also range, which is max - min.

Answer:

Step-by-step explanation:

The diagram is right angle triangle so we can use SOHCAHTOA

So in the diagram we have 62 degree opposite to x and the hypotenuse

Step 1

Sin62=x/16

Step 2

X=16sin62 by cross multiplication

Step 3

X=14.13

X=14

Please help me with this question

Natali5045456 [20]

Again, In this question too you need to substitute the given variable values into the original expressions. Here, "x" is given as a value of "12" and the variable of "y" is given as as value of "2". A single variable of "x" in the numerator is given in the expression. On the denominator the variable of "y" with a value of "2" is multiplied by a numbered value of "3". So, now showing this by the help of LaTeX.

$\mathbf{Since, \: x = 12, \: y = 2}$

$\mathbf{\therefore \quad \dfrac{12}{3 \times 2}}$

$\mathbf{\therefore \quad \dfrac{12}{6}}$

$\mathbf{2}$

$\boxed{\mathbf{\underline{\therefore \quad Final \: \: Answer \: \: is: \: B) \: 2}}}$

Hope it helps.
