Answer:
It will take Naomi 22 hours
Step-by-step explanation:
If they work together Mark, Naomi, and Yvonne take 11 hours, which means
three people represent 3* 11 = 33 man* hours
If they work alone Yvonne will take 5 man hours, and Mark will take 6* man hours.
Now we know that together they take 33 man hours therefore we have
5+ 6+ N = 33
Where N is Naomi's man* hours. We solve for N and get:
N = 33 - 11 = 22
N = 22
Naomi will take 22 hours to finish the job if she worked alone.
If the three sets of corresponding sides of two triangles are in proportion, the triangles are similar. SAS for similar triangles is NOT the same theorem as we used for congruent triangles.
According to the statement lines, r and s are parallel, then when a line intercepts both lines the angles formed are going to be the same.
Then x is at the same position as 156°.
