BRAINLIEST ASAP! PLEASE HELP ME :)

Mathematics
1 answer:
motikmotik3 years ago
6 0

Answer:

Step-by-step explanation:

1) ∠1 + 31 +69 = 180   {Angle sum property of triangle}

∠1 + 100 = 180

∠1 = 180 -100

∠1 = 80

2) Exterior angle equals the sum of opposite interior angles.

∠2 + 45 = ∠1

∠2 + 45 = 80

∠2 = 80 - 45

∠2 = 35

3)Exterior angle equals the sum of opposite interior angles.

∠3 + 47 = ∠1

∠3 + 47 = 80

∠3 = 80 - 47

∠3 = 33

Answer:


Step-by-step explanation:


In kilograms, just move the decimal right before the first digit and multiply it by ten to the power of how many times you moved the decimal:

6.20 x 10^6

In grams, change 6,200,000 kg to g.  One kg is 1000 g, so divide  6,200,000 by 1000.  This would equal 6200 g.  Now, move the decimal right before the first digit and multiply it by ten to the power of how many times you moved the decimal:


6.20 x 10^3

What is the length of the side labeled x cm?
UkoKoshka [18]
When we know 2 angles and one side, we use the Law of Sines.
First we need to find that third angle.
Angle A =
180 -41 -62 = 77 degrees

The Law of Sines states that

side a / Sine (A) = side x / Sine (X)
14 / Sine (77) = side x / Sine (41)

14 * Sine (41) / Sine (77) = side x

side x = 14 * 0.65606 / 0.97437
<span>side x = 9.18484 / 0.97437
</span>
<span> <span> <span> side x = 9.4264396482 </span> </span> </span>

How many sites are show in this data set?
andre [41]

Answer:

The total number of sites are 15 .

Step-by-step explanation:

As shown in question.

The number of sites in 2 shield darter = 3

The number of sites in 3 shield darter = 1

The number of sites in 4 shield darter = 4

The number of sites in 6 shield darter = 2

The number of sites in 7 shield darter = 3

The number of sites in 8 shield darter = 1

The number of sites in 9 shield darter = 1

Thus

Total number of sites =  Number of sites in 2 shield darter + Number of sites in 3 shield darter +  Number of sites in 4 shield darter +  Number of sites in 6 shield darter +  Number of sites in 7 shield darter  +  Number of sites in 8 shield darter + Number of sites in 9 shield darter

Putting the values in above

                                  = 3 + 1 + 4 + 2 + 3 + 1 +1

                                  = 15

Therefore the total number of sites are 15 .
