Answer:

The above triangle is an isosceles triangle....

Reason

As we can see AB and DE are parallel to each other

As angle ABC is 80 degree

Therefore BCE is too 80 degree (as they both are alternate to each others)

Hence angle DCB is a 50 degree because in the straight DCE we have angle BCE as <u>80 </u><u>degree</u><u> </u>and Angle ACD as <u>50 degree</u>

Since a straight line has <u>180 degree</u> therefore the remaining angle ACB is 50 degree(180-80-50)

Now in triangle BAC. Angle C is 50 degree and Angle B is 80 degree, since the total angle of a triangle is 180 degree therefore A is 50 degree that is angle BAC is 50 degree(180-50-80) .

Hence here we see that two opposite sides have same angle that is the reason its a ISOSCELES triangle

An old movie theater has seats on a main floor and in a balcony. The main floor has 26 rows of 29 seats in each row. The balcony
Archy [21]
The main floor has 26 rows of 29 seats each, that is 26*29 = 754 seats  
And in the balcony there is 8 rolls of 23 seats, that is 8*23 = 184 seats  
So the difference is 754 - 184 = 570   
Then the main floor has 570 seat more than the balcony
