Use the diagram to answer the question. What is the measure of ∠A? Enter the correct value. Do not enter the degree symbol.
forsale [732]

Answer:

Measure of ∠A = 60.07°

Step-by-step explanation:

From the figure attached,

ΔABC is a right triangle,

Measure of side AC = 15 units

and measure of side BC = 13 units

By applying Sine rule in this triangle,

SinA = \frac{\text{Opposite side}}{\text{Hypotenuse}}

Opposite side of angle A = Side AC

and hypotenuse of the triangle = Side BC

SinA = \frac{13}{15}

    A = \text{Sin}^{-1}(\frac{13}{15})

    A = 60.07°

Therefore, measure of angle A is 60.07°.

Plz help me this is already suppose to be done lol
nignag [31]

Answer:

1. 247 mg ÷ 10 = 24.7 cg

2. 247 mg ÷ 100 = 2.47 dg

247 mg ÷ 1000 = 0.247 g

Step-by-step explanation:

1. To convert from 'mg' to 'cg', you must divide by 10 because 'cg' consists of 10 mg.

2. To convert from 'mg' to 'dg', you must divide by 100 because 'dg' consists of 100 mg.

3. To convert from 'mg' to 'g', you must divide by 1000 because 'g' consists of 1000 mg.

What is the answer to 13x=32+5x
Ber [7]

Answer:

x = 4

Step-by-step explanation:

13x=32+5x

Subtract 5x from each side

13x-5x=32+5x-5x

8x = 32

Divide each side by 8

8x/8 = 32/8

x = 4

Please solve the table correctly.
Hitman42 [59]

Answer:

See below.

Step-by-step explanation:

No. Triangles       Perimeter

 1                                  14

2                                  18

3                                  22

We see from the table, after the first  perimeter  (= 14),  with  each increase of 1 in the number of triangles,  the perimeter increases by 4.

As an equation it is  P = 14 + 4(n - 1)  where P = perimeter and n = number of triangles.
