Answer:
122 degrees, because x and z are alternate interior angles
122 degrees, because 58 degrees and z are same side interiors which add to 180
Step-by-step explanation:
1) we know that
m∠x=m∠z -----> by alternate interior angles
m∠x+58°=180° ----> by supplementary angles (form a linear pair)
m∠x=180°-58°=22°
therefore
m∠z=22°
2) m∠z+58°=180° ----> by same side interior angles
solve for z
m∠z=180°-58°=122°
therefore
122 degrees, because x and z are alternate interior angles
122 degrees, because 58 degrees and z are same side interiors which add to 180
B, 2 5/8.
2 and 5/8 times itself is 5 1/4, meaning its half of 5 1/4.
Answer:6a+75
Step-by-step explanation:
5+2a+22+22+1+1+22+4a+3
add 22,22,1,1,22,5, and 3
2a+4a+75
6a+75
10 trees / 2 hours = 5 trees per hour
150 trees / 5 per hour = 30 hours
if we take 31 to be the 100%, what is 28 off of it in percentage?
![\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 31&100\\ 28&x \end{array}\implies \cfrac{31}{28}=\cfrac{100}{x}\implies 31x=2800\implies x=\cfrac{2800}{31} \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ ~\hfill x\approx 90.32~\hfill](https://tex.z-dn.net/?f=%5Cbf%20%5Cbegin%7Barray%7D%7Bccll%7D%20amount%26%5C%25%5C%5C%20%5Ccline%7B1-2%7D%2031%26100%5C%5C%2028%26x%20%5Cend%7Barray%7D%5Cimplies%20%5Ccfrac%7B31%7D%7B28%7D%3D%5Ccfrac%7B100%7D%7Bx%7D%5Cimplies%2031x%3D2800%5Cimplies%20x%3D%5Ccfrac%7B2800%7D%7B31%7D%20%5C%5C%5C%5C%5B-0.35em%5D%20%5Crule%7B34em%7D%7B0.25pt%7D%5C%5C%5C%5C%20~%5Chfill%20x%5Capprox%2090.32~%5Chfill)
