Right triangle xyz has a right angle at vertex y and a hypotenuse that measures 24 cm. angle zxy measures 70o.
what is the length of line segment xy? round to the nearest tenth.
8.2 cm
8.7 cm
22.6 m
25.5 cm

consider right triangle xyz with right angle y (see attached diagram). the measure of angle x is 70°.

use the definition of the cosine of the angle:

in triangle xyz,

then

answer: correct coice is a

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
