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

If the ratio of the length to the breadth of a rectangle be 5:3 and its perimeter is 144m find the length of the rectangle
Kamila [148]

Answer:

length=45 m (2 sides = 90m)

Step-by-step explanation:

5x +3x=144

8x=144

x=18 (each of the 8 parts of 144 measure 18m)

5(18) + 3(18)=144

90 +54=144

90/2=45 (1 length side)

54/2=27 (1 width side)

The rectangle= 45+45 +27+27 = 144
