Find the measure for angle f 46 34 122 58

xxMikexx [17]

Answer:

$\angle f = 122\degree$

Step-by-step explanation:

$\angle d = 58\degree$ (vertical angles)

$\angle f+\angle d= 180\degree$

(Interior angles on the same side of transversal)

$\angle f+ 58\degree = 180\degree$

$\angle f = 180\degree-58\degree$

$\huge \orange {\boxed {\angle f = 122\degree}}$

A company that offers tubing trips down a river rents tubes for a person to use for $20 and “cooler” tubes to carry food and wat

Licemer1 [7]

Answer:

The number of each type of tube does the group rent is 11 tubes for person and 4 “cooler” tubes to carry food and water

Explanation:

The rents for tubes for a person to use = $20

The rents for “cooler” tubes to carry food and water = $12.50.

The rent for a total of 15 tubes = $270

11 tubes whose rent cost $20 = $11 \times 20$

= 220

4 “cooler” tubes rent cost $12.50 = $4 \times 12.5$

= 50

Therefore for 15 tubes = 11 +4= 15

cost = 220 + 50

=270

The number of each type of tube does the group rent is 11 tubes for person and 4 “cooler” tubes to carry food and water
