Answer:

60

Step-by-step explanation:

All the sides are equal, which makes it an equilateral triangle.

That means all the angles are equal

180/3 = 60

Angle A is 60 degrees

Answer:

60 degrees

Step-by-step explanation:

This triangle has 3 sides that are all 61 units. Therefore, this triangle must be equilateral, because all of the sides are equal.

In an equilateral  triangle, all the angles are equal and add to 180 degrees.

Therefore, we can say that, if x represents an angle,

3x=180

Now, solve for x, by isolating x. 3 and x are being multiplied, so divide both sides by 3 (division is the opposite of multiplication)

3x/3=180/3

x=180/3

x=60

The measure of angle A is 60 degrees

Number 4

6/18*9/42= 1/3*3/14= 3/42= 1/14

Number 5

22/15*45/4= 33/2=16 1/2

Number 6

3/28* 35/6= 105/168= 5/8

Number 7

2/7*35/12=60/84=5/6

Number 8

A man walks at the rate of 88 paces to the minute if the average length of his paces is 0.875m, find the time take to walk 2.31k
Nataly [62]

Answer:

30 minutes

Step-by-step explanation:

Walk rate = 88 paces/ minute

Average length of pace = 0.875 m

Time taken to walk 2.31 km ;

The distance in metres :

1000 m = 1 km

2.31 km = (1000 * 2.31) = 2310 m

Recall :

Time taken = distance / speed

Distance walked in a minute = 88 * 0.875 = 77 m

Time taken = 2310 / 77

Time taken = 30 minutes

two angles are supplementary one angle measures 75% more than twice the measure of the other what are the measurement of the two
valkas [14]
Let's call the angles x and y. We know that supplementary angles must add to 180 degrees, so x+y=180.

Furthermore, we know that x is 75% more than 2y. We can write "75% more than" numerically as 1.75, so x = 1.75(2y).

We can simplify the second equation by multiplying 1.75 and 2 together to get x = 3.5y.

Now we can solve the system of equations by substitution by plugging 3.5y in for x in x+y=180.

(3.5y) + y = 180

Combine like terms.

4.5y = 180

Divide by 4.5

y = 40

Plug y = 40 in and solve for x.

x + 40 = 180

x = 140

The answer is 40 and 140. Hope this helps :)
