Answer:

False

Step-by-step explanation:

1) If a triangle has two congruent sides, then we are dealing with an isosceles triangle. If a triangle has two congruent sides and it is a 45º,45º,90º it's a special case of an isosceles triangle called Right Isosceles Triangle.

The Sum of its interior angles must be equal to 180º always!

2) Check it out below an example of an Isosceles Triangle. ∠E≅∠G

The roller skating rink has a perimeter of 150 yards. If the length of is twice as long as the width,what are the dimensions of
Alexeev081 [22]

Answer: 50 yards by 25 yards

Step-by-step explanation:

rink is also a rectangle

perimeter= 150 yards

length= 2x

width=x

the perimeter of rink is:

p=2(length + width)

150=2(2x + x)

150= 2(3x)

150= 6x

x=150 / 6

x=25

so width is 25 yards and length is twice the width which is 2x

length= 2× 25

length= 50 yards

so the dimension is 50 yards by 25 yards

Why 1975 can't be the sum of two squares. Or prove that the equality x ^ 2 + y ^ 2 = 1975 has no solutions in integers
Amanda [17]

Answer:

Step-by-step explanation:

If a number can be expressed by sum of two square, only if the number can be represented by 4k + 1 form

1975 = 4*493 + 3

So, 1975 can't be a sum of two squares

The difference of twice a number and five is three. Find the number.
Paraphin [41]

Step-by-step explanation:

Difference means minus

Twice a number mean 2 times a number, let's say 2x

Is means equals

So translated to an equation is:

2x - 5 = 3

Then isolate x so add 5 to both sides

2x = 8

Then divide by 2

X = 4

Calculate the force of gravity on earth of an object that has a mass of 200 kg. A. 1,962 N B. 123 N C. 20 N D. 326 N
leonid [27]

For this case we have that by definition, the gravity of the earth is given by:

g = 9.807 \frac {m} {s ^ 2}

On the other hand, Newton's second law states:

F = M * g

Where:

F: It's the force

M: It's the mass

g: Acceleration of gravity

F = 200 * 9.807\\F = 1961.4 \ N

Answer:

Option A
