Answer:

<em>34.2 ; 105.8 ; 12.0</em>

Step-by-step explanation:

\frac{a}{sinA} = \frac{b}{sinB} = \frac{c}{sinC}

c² = a² + b² - 2abcosC

~~~~~~~~~~~~

sinB = \frac{bsinA}{a}

sinB = 7sin40° ÷ 8 ≈  0.562439

<em>m∠B</em> ≈ <em>34.2°</em>

<em>m∠C</em> = 180° - ( 40° + 34.2° ) = <em>105.8°</em>

c² = 8² + 7² - 2(8)(7)cos106° ≈ 143.87

<em>c </em>≈ <em>12.0 </em>units

Franklin rolls a pair of six-sided fair dice with sides numbered 1 through 6.
Zarrin [17]

Answer:

The answer is 7/36.

Step-by-step explanation:

First, you find out how many possible outcomes there are from rolling a pair of dice. On one cube, you can roll a 1,2,3,4,5, or 6; so there are 6 outcomes. Since there are two cubes, you multiply 6 by itself to get a total of 36 possible outcomes. Next, you find the probability of the sum of the numbers rolled being an even number; the possibilities are 2,4,6,8,10, or 12, which is 6/36. The probability of rolling a multiple of 5; the one possibility is just 5, since we already accounted for rolling a 10 as an even number. So that is 1/36. The word <u>or</u> says that we add the two probabilities, so the final answer is 6/36+1/36=7/36.

-12+x-34=60<br> If you like this question please rate this five stars!<br> Thank you!
natulia [17]

Answer:

x=106

Step-by-step explanation:

Let's solve your equation step-by-step.

−12+x−34=60

Step 1: Simplify both sides of the equation.

−12+x−34=60

−12+x+−34=60

(x)+(−12+−34)=60(Combine Like Terms)

x+−46=60

x−46=60

Step 2: Add 46 to both sides.

x−46+46=60+46

x=106
