Answer:

B) x + 20 ≥ 50

Step-by-step explanation:

Given,

The hours she already has for social studies = 20,

After getting x more hours,

The total hours she has now = x + 20,

According to the question,

Total hours ≥ 50

\implies x + 20\geq 50

Which is the required inequality to model give situation,

Hence, OPTION B is correct.

We need to attach a support wire to Glendale's flagpole, which is 24 feet high. The
antoniya [11.8K]

Step-by-step explanation:

this creates a right-angled triangle.

the right angle (90°) being the angle between flag pole and ground.

the angle ground-wire is 50°.

because we know that the sum of all angles in a triangle is always 180°, we know then that the angle flagpole-wire is

180 - 90 - 50 = 40°

so, we have the situation to know 1 side and all angles.

to get the other sides we use best the law of sine :

a/sin(A) = b/sin(B) = c/sin(C)

where the sides and related angles are always opposite of each other.

in our case now we have

24/sin(50) = wire/sin(90) = wire/1 = wire = 31.32977494... ft

so, the rounded answer is that the wire must be

31.3 ft long
