Question

Please help I'm almost done the test and need this and one other question ​

Answer 1

Answer:

$z=68$

Step-by-step explanation:

Use the formula $180\times(n-2)$ to find the sum of the angles in a polygon, given n sides. This formula tells us the angles of this pentagon must add to 540 ($180\times(5-2)=540$).

So, we can setup an equation:

$70+2z+11+119+z+2z=540$

Solve for z:

$200+5z=540$ Combine like terms

$5z=340$ Subtract 200

$z=68$ Divide by 5

Therefore, the value of z = 68.
