So the total value of a triangle is 180°

So when u calculate the missing angle its value is 42°

180°-(60°+78°) = 42°

Answer:

a = 5.3

<C = 42°

Step-by-step explanation:

<C = 180 - (60 + 78)

<C = 42°

Law of sines:

a/sin(60) = 6/sin(78)

a = sin(60)*6 / sin(78)

a = 0.866 * 6 / 0.978

a = 5.3

Answer:

x=81.25, A=65, B=94, C=21

Step-by-step explanation:

corresponding angles of similar triangles are equal, hence angle measurements of A, B, and C. To solve for x, set up a ratio (60/48=x/65) and solve

Complete the table by supplying the measure of inscribed angle and its intercepted arc

Nadusha1986 [10]

Answer/Step-by-step explanation:

Based on the inscribed angle theorem, any inscribed angle = ½ of its intercepted arc

Thus:

✔️Inscribed angle = 57°

Intercepted arc would be: 2*57 = 114°

✔️Intercepted arc would be: 123°

Inscribed angle = ½(123) = 61.5°

✔️Intercepted arc would be: 46°

Inscribed angle = ½(46) = 23°

✔️Inscribed angle = 69°

Intercepted arc would be: 2*69 = 138°

✔️Intercepted arc would be: 155°

Inscribed angle = ½(155) = 77.5°

The table below shows the relationship between the number of calories burned and the minutes of exercise.

sergejj [24]

Answer:

Option B

Step-by-step explanation:

Since, number of calories 'C' burned is proportional to the number of minutes (m) given to the exercise,

C ∝ m

C = km

Where k is the proportionality constant.

From the table attached,

For C = 250 calories and m = 30 minutes,

250 = 30k

k = $\frac{250}{30}$

= $\frac{25}{3}$

Therefore, equation representing this situation will be,

C = $\frac{25}{3}m$

Option B will be the correct option.
