Answer:

B = 54°; a ≈ 1.86; b ≈ 4.19

Step-by-step explanation:

The remaining angle is ...

B = 180° -105° -21° = 54°

The law of sines tells you the side lengths are in proportion to the sines of the angles:

a = 5·sin(A)/sin(C) ≈ 1.86

b = 5·sin(B)/sin(C) ≈ 4.19

Together, teammates Pedro and Ricky got 2688 base hits last season. Pedro had 284 more hits than Ricky.
Yakvenalex [24]

Answer:

Pedro got 1486 and Ricky got 1202 hits

Step-by-step explanation:

We have that, teammates Pedro and Ricky together got 2688 base hits last season.

This means p+r=2688, where p is the number of hits Pedro got and r number of hits Ricky got.

Also Pedro had 284 more hits than Ricky.

This gives us:

p=r+284

We substitute this last equation into the first one to get:

r+284+r=2688

2r=2404

Divide by 2 to get:

r=1202

Therefore p=1202+284=1486

2/3 - 10/9and5/3 and 7/9
agasfer [191]

Step-by-step explanation:

always Pythagoras with the coordinate differences as sides and the distance the Hypotenuse.

c² = (2/3 - 5/3)² + (-10/9 - -7/9)² = (-3/3)² + (-10/9 + 7/9)² =

= (-1)² + (-3/9)² = 1 + (-1/3)² = 1 + 1/9 = 10/9

c = sqrt(10)/3
