Mathematics

3 0

Answer:

A = 19.47

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

sin theta = opp / hypotenuse

sin A = 2/6

Take the inverse sin of each side

sin ^-1 ( sin A) = sin ^-1 (2/6)

A =19.47122063

To the nearest hundredth

A = 19.47

Answer:

Portion of walking in degrees = 72°

Step-by-step explanation:

The question is incomplete as the diagram is not shown in the question. I have attached the full question below. Consult it to understand the solution better

First calculate the percentage of walking from a total of all activities.

Percentage of walking = 10/50 · 100%

Percentage of walking = 20%

It means the portion of the circle(pie chart) for walking should be equal to 20% of the whole circle.

We know that the whole circle is equals to 360°

Circle = 360°

We need to calculate 20% of 360°, which will represent the portion of walking in degrees.

Portion of walking in degrees = 20/100 · 360°

Portion of walking in degrees = 72°

List multiples to find LMC of 27 and 45
PtichkaEL [24]

Answer:

135

Step-by-step explanation:

I think you mean the LCM instead of LMC. LCM stands for Least Common Multiple. Anyway, some of the multiples of 27 are 27, 54, 81, 108, and 135. Some multiples for 45 are 45, 90, 135. We can see here that 27 and 45 share the mutiple of 135 which is the first number they have in common.
