Solve the inequality: 3z−1≤−7

Select one:

z≥2

z≥−2

z≤−2

z≤2

Step-by-step explanation:

1) Add 1 to both sides.

2) Simplify -7 + 1 to -6.

3) Divide both sides by 3.

4) Simplify 6/3 to 2.

Therefor, the answer is Option C.

if i'm not wrong, i would say that the third angle has (72) because the three sides of all triangles have 180 degrees and if we subtract 180 - 62 - 40 = (72) / but i'm not sure about 40 yd.
