Question
the diagram shows a triangle.
what is the value of z?
z = \boxed{\circ}
submit
Step1: Recall triangle angle sum
The sum of angles in a triangle is \(180^\circ\). So, \(2z + 5z + 35^\circ = 180^\circ\).
Step2: Combine like terms
Simplify the left side: \(7z + 35^\circ = 180^\circ\).
Step3: Solve for z
Subtract \(35^\circ\) from both sides: \(7z = 180^\circ - 35^\circ = 145^\circ\)? Wait, no, wait: \(180 - 35 = 145\)? Wait, no, \(2z + 5z = 7z\), so \(7z + 35 = 180\). Subtract 35: \(7z = 145\)? Wait, no, 180 - 35 is 145? Wait, no, 180 - 35 is 145? Wait, no, 180 - 35 = 145? Wait, no, 180 - 35 is 145? Wait, no, 180 - 35 = 145? Wait, no, I made a mistake. Wait, 2z + 5z + 35 = 180. So 7z = 180 - 35 = 145? Wait, no, 180 - 35 is 145? Wait, no, 180 - 35 = 145? Wait, no, 180 - 35 is 145? Wait, no, 180 - 35 = 145? Wait, no, 180 - 35 = 145? Wait, no, 180 - 35 = 145?
