Answer:
34
Step-by-step explanation:
The triangle with the 28 degree angle is an isosceles as it has 2 sides which are the same length. This means the other angle opposite to one of the sides that is the same length is also 28. The sum of all the angles in the triangle is 180. To find the 3rd angle we just add the two 28 degree angles and subtract it from 180. 180-56=124. The angle of 124 is on a straight line which is divided by another line. The other side of the lines angle will be 180-124 as the angle of a straight line is 180 degrees. 180-124=56. Now we have two angles in the triangle which contains x, 90 degrees and 56 degrees. Once more the total of all angles in the triangle is 180 so subtract the other two angles to get x, 180-(90+56)=34.
First, we must follow PEMDAS. (Parenthesis, exponents, division, multiplication, addition, and subtraction.).
We do what's in the parenthesis first.
9+9(2+4)÷3-2.
2+4=6.
Now our problem looks like this;
9+9(6)÷3-2
OR
9+9×6÷3-2.
Anything in a parenthesis with no sign next to it, like this; 8(2), just means multiplication, so it would look like this: 8×2.
Next, we do all the multiplication in our problem.
9+9×6÷3-2.
9×6=54.
Now our problem looks like this;
9+54÷3-2.
Next, we do the division.
9+54÷3-2
54÷3=18.
Now our problem looks like this;
9+18-2.
Next, we do the addition.
9+18-2
9+18=27
Now it looks like this;
27-2.
Finally, we subtract.
27-2=25.
Your final answer is 25!
Have a nice day! :)
