Because angles in a triangle add up to 180, you can add up the given angles and then take that answer away from 180, so:
65 + 74 = 139
180 - 139 = 41°
So your answer is 41°, I hope this helps!

the answer is 41 degrees

a triangle has 180degrees, is two of the angles add to equal 139 then subtract that from 180 and you get your answer if 41

Whats f? 0.62(f + –6) + 6.96 = 8.2
Semmy [17]

Answer:

f=8

Step-by-step explanation:

0.62(f+(-6)+6.96=8.2

0.62(f-6)+6.96=8.2

multiply both sides by 100

0.62(f-6)*100+6.96*100=8.2*100

Refine

62(f-6)+696=820

Subtract 696 from both sides

62(f-6)+696-696=820-696

Simplify

62(f-6)=124

Divide both sides by 62

62(f-6)/62 = 124/62

Simplify

f-6=2

add 6 to both sides

f-6+6=2+6

simplify

f=8

Side AB is 18, Side AC is 9, Side BC is 5. Find the SinA. Give your answer in fraction and decimal form.
Sladkaya [172]

Input data

In any right triangle, the sine of an angle x is the length of the opposite side (O) divided by the length of the hypotenuse (H). In a formula, it is written as 'sin' without the 'e':

\begin{gathered} \sin A=\frac{5}{18} \\ \sin A=0.277 \end{gathered}

slader How many partitions of the set {1, 2, 3, . . . , 100} are there such that there are exactly three parts and elements 1, 2
My name is Ann [436]

Answer:

3^{97} partitions.

Step-by-step explanation:

As we know if we have x number of elements we can arrange them in x! ways.

here we have 100 elements so we can arrange them in 100! ways.

Now if we have exactly three parts and 1,2 and 3 are in different parts then let consider 1 goes to part 1, 2 goes to part 2, and 3 goes to part 3. For the remaining 97 elements,  we have three options for each element, thus we can arrange the remaining 97 elements in 3^{97} ways/partitions.

each of these partition will contain only three elements.

The earned run average (ERA) a of a baseball pitcher varies directly as the number of earned runs r and inversely as the number
7nadin3 [17]

Answer:

The number of earned runs is 28.

Step-by-step explanation:

Earned runs average:

The earned runs average of a pitcher is the number of runs the he/she gives each 9 innings on average.

Find the number of earned runs when the pitcher has an ERA of 2.25 after pitching 112 innings in the next season.

Solved by proportions, using a rule of three.

For each 9 innits, the pitcher gives 2.25 runs. How many runs for 112 innings?

9 innings - 2.25 runs

112 innings - x runs

Applying cross multiplication:

9x = 2.25*112

x = \frac{2.25*112}{9}

x = 28

The number of earned runs is 28.
