Answer:

49.03 degrees

Step-by-step explanation:

c = 49, $\alpha$ = 41

We can solve for $\beta$ if we first find b.

Remember: SOH CAH TOA

Cosine = Adj/Hypotenuse

So, Cos (41) = b/49

49 x (Cos 41) = b

49 x .755 = b

b = 36.99

sin $\beta$ = Opp/Hyp = b/49 = 36.99/49 = .755

β = inverse sin (.755) = 49.03° (Inverse sin is designated by sin⁻¹ on your calculator)

Here is Triangle A. Lin created a scaled copy of Triangle A with an area of 72 square units. C. What is the length of bottom sid

satela [25.4K]

Answer:

The length of bottom side of the scaled copy is 12 u

Step-by-step explanation:

To solve this problem we have to know that to calculate the area of a triangle we use the following formula

a = area

b = base

h = height

a = b * h

In the triangle A the base and the height are equal to 3

b = h

Now that we know that b & h we can calculate the base of the scaled copy

72 u² = b * b

72 u² = (b)²

√(72 u²) = b

12 u = b

The length of bottom side of the scaled copy is 12 u

3k-2=10 whats the answer

kap26 [50]

Answer:

k = 4

Step-by-step explanation:

3k - 2 = 10

3k - 2 + 2 = 10 + 2 (adding 2 to both sides)

3k = 12

3k/3 = 12/3 (dividing both sides by 3)

k = 4

Happy to help :)

Find the midpoint of the segment with the following endpoints.<br> (8,4) and (2,7)

Fudgin [204]

Answer:

Step-by-step explanation:

Use the midpoint formula: $\frac{ChangeInX}{2} ,\frac{ChangeInY}{2}$

So, the Change In X is 2-8 = -6

And the Change in Y is 7-4 = 3

Once you divide both of the changes by 2, you get

X: -3

Y: $\frac{3}{2}$

So the midpoint is: $(-3,\frac{3}{2})$
