Answer:

82.5°

Step-by-step explanation:

This is the case of a isosceles triangle , as you may know in a isosceles triangle , there are two sides of equal length as well as two equal angles.

You know that the sum of angles in a triangle is 180°, therefore it comes to this equation :

15° + 2x = 180°

2x = 165°

x = 82.5°

therefore 82.5° is the correct answer.

What ls 6q+m-m; use m=8and q =3
SpyIntel [72]
First of all, I see  +m  and  -m  on the left side, and I realize that when you combine those, they make zero-m.  So you can ignore them completely,
and that means that the value of 'm' has no effect on the value of that
expression.  It doesn't matter whether 'm' is  2.509  or 'm' is  8  or 'm'
is 9 hundred trillion.  Either way, the expression has the same value.

The value is   6q = 6(3) = <em>18</em> .

Without dividing,estimates the quotient for 3,328 divide by 6
Katarina [22]

Answer:

For this equation let's round the 3328 to a 3300.

Step-by-step explanation:

If we remove the 2 zeros, we remain with a 33. 33/6 is 5.5 Now if we add back 2 places we get 550. I know this is written badly, but I hope it helped.
