Answer:
The total number of students in the school is 750. You can use algebraic equation to calculate the number of the students. Let x be the total number of students in the school. Hope this helps.
so one: the middle Angles are all 90 degrees triangles equal 180, the angle opposite of "x" is equal to 34 so 180-90-34=x
two: both angles are equal set it up like an equation and solve for n
three: the corner angle of the right triangle is equal to 61 as well again do 180-(61×2)=x
4: do this equation (<ktu)2+ x = 180 then solve for x
5: not exactly.sure what its asking
hope this helps
3x - 7 = 2x - 5<em> add 7 to both sides</em>
3x = 2x + 2 <em>subtract 2x from borh sides</em>
<h3>x = 2</h3>
Check:
L = 3(2) - 7 = 6 - 7 = -1
R = 2(2) - 5 = 4 - 5 = -1
L = R CORRECT! :)
Answer is 750
