If 2 angles are both right angles then they are congruent. Would the converse of this statement be true?
yKpoI14uk [10]

Given:

The statement is: If 2 angles are both right angles then they are congruent.

To find:

The converse of the given statement and then check whether it is true or not.

Solution:

We know that,

Statement: If p, then q.

Converse : If q, then p.

The statement is: If 2 angles are both right angles then they are congruent.

So, the converse of this statement is:

If 2 angles are congruent then both are right angles.

This statement is not true because if 2 angles are congruent then it is not necessary that the angles are right angles.

Therefore, the converse of this statement is not true.

She didn’t notice that the 3 and the 4 both do not have the variable “n” with them

One fifth of sum of two angles is 24 and their diffetence is 14 find the two angles​
Serggg [28]

Answer:

Angles are 67^0,53^0

Step-by-step explanation:

Let the angles be x,y

One fifth of sum of two angles is 24

\frac{x+y}{5} =24\\\\x+y=120

The  difference is 14

x-y=14

2x=134\\\\x=67^0

y=120-67\\\\=53^0

I need help on this question, think any of you guys could help?
levacccp [35]

Answer:

We need to find the circumference, and in order to find the circumference we must know the formula for it.

Formula for circumference of a circle;

a = 2πr

Where π is the pi(3.14 or 22/7), and r is the radius which is half of the diameter.

Since we are given the diameter, we need to find the radius. So 1/2 of the diameter (26 x 1/2) = is 13

Now we just plug in the actual values in the formula:

a = 2πr

a = 2 x 3.14 x 13

a = <u>18.84 feet</u>

But now, we need to find how many revolutions it would take to get to 500 feet.

So we divide 500 feet by 18.84 feet;

500/18.84 = 26.53, around 27 revolutions.
