If we know that line $AB$ is equal to line $AD$ , then this means that ∠ $ADB$ has to be equal to ∠ $ABD$ in order to form a closed triangle. All angle measures of a triangle add up to $180$ °, so use the equation: $2(35) + x = 180$ .

70 + x = 180

Subtract 70 from both sides to isolate x:

180 - 70 = 110

110 = x

Hope this helped.

Anvisha [2.4K]

Answer:

x = 8

Step-by-step explanation:

40 + 6x + 2 = 90 {Complementary angles}

Combine like terms

40+ 2 + 6x = 90

42 +6x = 90 {Subtract 42 form both sides}

6x = 90 - 42

6x = 48 {divide both sides by 6}

6x/6 = 48/6

x = 8

Answer:

Expected value of the game: -$0.421

Expected loss in 1000 games: $421

Step-by-step explanation:

There are two possible outcomes for the event:

- There is a 1 in 38 chance of winning $280

- There is a 37 in 38 chance of losing $8

The expected value for a single game is:

$E(X) = \frac{1}{38}*\$280-\frac{37}{38}*\$8\\E(X)=-\$0.421$

The expected value of the game is -$0.421

In 1,000 plays, the expected loss is:

$L = 1,000*-\$0.421\\L=-\$421$

You would expect to lose $421.
