z = 4/5
If you take the cube roots of 64 and 125, you get 4 and 5 respectively.
Answer: acute angle, straight line
Step-by-step explanation:

The shown pair of angles are Co interior angle pair, therefore the sum of those angles is 180°






The required value of x is 7°
First multiply 3 and the 1
Then simplify b^2-4b+3=0
Then divide both numbers by 3 (b-3/3)(b-1/3)=0
If it doesn’t go in even like the second term then bring it before the B
Then equal both terms to 0 and solve
