Nostrana [21]

Answer:

He must lose 4.4 pounds per week.

Step-by-step explanation:

Buffalo Bill currently weighs 202 lb. He wants to weigh 180 lbs for his reunion.

This means that he needs to lose 202 - 180 = 22 lb.

35 days from today.

Each week has 7 days. So this is 35/7 = 5 weeks from now.

How many pounds per week must he lose?

22 pounds in 5 weeks, that is 22/5 = 4.4 pounds per week.

Solve for x in the triangle<br> A 25.6<br> B 27.8<br> C 45.6<br> D 64.4
labwork [276]

Answer:

The measure of angle x is 64.4\°

Step-by-step explanation:

To find the measure of angle X, apply the law of cosines

The law of cosines states that

c^{2}=a^{2}+b^{2}-2(a)(b)cos(C)

In  this problem we have

a=19\ cm

b=25\ cm

c=24\ cm

C=x\°

substitute

24^{2}=19^{2}+25^{2}-2(19)(25)cos(C)

576=986-950cos(C)

cos(C)=(986-576)/950

C=arccos[(986-576)/950]=64.4\°

Therefore

The measure of angle x is 64.4\°
