The perimeter of a rectangle is given by P equals 2 l plus 2 w. Find the width of a rectangle whose length is 35 and perimeter i
maks197457 [2]
2l + 2w = P
l = 35,  P = 84,  w=?

2*35 + 2*w = 84
70 + 2w = 84
2w = 84 - 70
2w = 14
w = 14/2
w = 7 in

In engineering, equilateral triangles can support the most weight and so are commonly found in the design of bridges and buildin
Dafna1 [17]

Answer:

60°

Step-by-step explanation:

Am equilateral triangle is a triangle that has all its sides and angles equal. Note that an equilateral triangle has 3 sides and angles.

Let the angles be a, b and c

The sum of angle in a triangle is 180°, hence;

a+b+c = 180°

Since a = b = c

The equation becomes;

a+a+a = 180°

3a = 180

a = 180/3

a = 60°

Hence the measure of the angles of an equilateral triangle is 60° for the three angles.
