if a triangle is an equilateral triangle then the triangle has exactly three 60 angles abc is an equilateral triangle

Artist 52 [7]

Answer:

The statement is always TRUE

Step-by-step explanation:

An equilateral triangle has all angles and all sides equal

The sum of angles in a triangle is 180 degrees.

Let each of the angles be x degrees.

Then we solve the following equation for x.

$x+x+x=180\degree$

$\implies 3x=180$

$\implies x=\frac{180}{3}=60\degree$

Multiplying a number by 4/5 then dividing by 2/5 is the same as multiplying by what number?

Verizon [17]

Would it be 33/10? If you are multiplying and then division you would use the inverse of the divided fraction and multiply. So you could invert 2/5 to 5/2 and add to 4/5. After finding the common denominator it would be adding 8/10 + 25/10 = 33/10.

If 7x is an odd integer, represent the next odd integer as an algebraic expression in x.

blagie [28]

Given :

7x is an odd integer.

To Find :

The next odd integer as an algebraic expression in x.

Solution :

All positive integers are :

1 , 2 , 3 , 4 , 5 , ......

From the above series we noticed that every other odd number is 2 more than the previous one.

So , 7x is an odd number.

Therefore, next odd number is 7x + 2.

Hence, this is the required solution.

natali 33 [55]

Answer:

90ft

Step-by-step explanation:

I draw it out and add a dotted line to make a triangle and rectangle then you find the area of them individually and add the two together.

Rectangle:

6*3=18

Triangle:

Add the 6+6 together to get the height of the triangle and subtract the 3 from the 15 to get the base

(12*12) $\frac{1}{2}$

144/ $\frac{1}{2}$

Total area:

18+72
