Two similar triangles are shown below: which two sets of angles are corresponding angles? a. ∠a and ∠d; ∠b and ∠c b. ∠a and ∠c; ∠b and ∠d c. ∠a and ∠e; ∠b and ∠d d. ∠a and ∠e; ∠b and ∠c

Which sum or difference identity would you use to verify that cos (180° - ∅) = -cos ∅? a. sin (α -β) = sin α cos β – cos α sin β b. cos (α -β) = cos α cos β – sin α sin β c. cos (α -β) = cos α cos β + sin α sin β d. sin (α + β) = sin α cos β + cos α sin β

Suppose that a households monthly water bill (in dollars) is a linear function of the amount of water the household uses (in hundreds of cubic feet, hcf). when graphed, the function gives a line with slope of 1.65. if the monthly cost for 13 hcf is $46.10 what is the monthly cost for 19 hcf?
