Answer:

Step-by-step explanation:

Congruent figures in geometry are identical in shape and size. Congruent figures have congruence. That seems simple enough, but congruent figures need not be turned the same way or face the same direction to be congruent.

∠1 and ∠2 are complementary angles. If ∠1 measures 35º, what is the measure of ∠2?

max2010maxim [7]

Answer:

55 degrees

Step-by-step explanation:

Complementary angles are two angles that equal 90 degrees together so if one angle is 35 degrees then the other must be able to add towards that to make 90 degrees

90=35+∠2

-35 -35

55=∠2

How do you find the distance between -2 and 3 on a number line

Masteriza [31]

If you draw the line and mark -2 and 3 you find that they are 5 apart. By calculation, subtract the lowest from the highest: 3 - -2 = 3+2 = 5

Suppose a person offers to play a game with you. In this game, when you draw a card from a standard 52-card deck, if the card is

AlexFokin [52]

Answer:

Your expected loss per game is of $0.31.

Step-by-step explanation:

In a standard 52-card deck, we have that:

There are 12 face cards.

What is your expected gain or loss (in dollars) per game?

12/52 probability of winning $2.

1 - 12/52 = 52/52 - 12/52 = 40/52 probability of losing $1. So

$E = \frac{12}{52}*2 - \frac{40}{52}*1 = \frac{24 - 40}{52} = -\frac{16}{52} = -0.31$

Negative, so a loss is expected.

Your expected loss per game is of $0.31.

X<= -2 on a number line

ruslelena [56]

Answer:

$x\le \:-2\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\le \:-2\:\\ \:\mathrm{Interval\:Notation:}&\:(-\infty \:,\:-2]\end{bmatrix}$

Please check the attached number line graph.

The number line clearly indicates that the graph is heading towards negative infinity from -2.

Step-by-step explanation:

Given the inequality expression

x ≤ -2

The inequality symbol ' ≤ ' means 'less than or equal to'.

Thus,

x ≤ -2 means x is less than or equal to -2.

In other words,

$x\le \:-2\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\le \:-2\:\\ \:\mathrm{Interval\:Notation:}&\:(-\infty \:,\:-2]\end{bmatrix}$

Please check the attached number line graph.

The number line clearly indicates that the graph is heading towards negative infinity from -2.
