Answer:

Option A -- 30 degrees.

Step-by-step explanation:

Knowing two legs of the triangle, 6 and 6\sqrt{3}, we know that this is a 30-60-90 triangle since the measurements match the requirements. Therefore, the last angle is 30 degrees.

Answer:

∅ = 30°

Step-by-step explanation:

given data

side 1 = 6 inches

side 2 = 6\sqrt{3}  inches

to find out

angle opposite the leg that is 6 inches long

solution

we  will use pythagoras theorem that is express as

hypotenuse² = perpendicular²   + base²     .......................1

put here value and we get  hypotenuse

hypotenuse² = 6² + (  )²

solve it we get

hypotenuse²  = 144

hypotenuse = 12 inches  

now we apply here sin∅ that is

sin∅ = \frac{perpendicular}{hypotenuse}     ................2

put here value and we get

put here value and we get

sin∅ = \frac{6}{12}  

∅ = sin^{-1}(0.5)  

solve it we get

∅ = 30°

FinnZ [79.3K]

Answer:

Hence, a carpenter can paint a maximum of 7 chairs.

Hence, option A is correct.

Step-by-step explanation:

A carpenter has less than 120 min. to spend painting furniture each day.

Today, he has spent 30.5 min. painting a desk.

Now he will paint x chairs, each of which takes 12.5 min.

i.e. he will take a total of 12.5x minutes in painting 'x' chairs.

Also total time spent on painting furniture each day will be equal to time spent on painting a desk and all of the chairs.

Hence,

30.5+12.5x<120 (since the total time he spends on painting is less than 120 mins.)

⇒ 12.5 x<120-30.5

⇒ 12.5 x<89.5

⇒ x<7.16  ( on dividing both side of the inequality with 12.5)

Hence, a carpenter can paint a maximum of 7 chairs.
