6 0

Answer:

  1.  7.1 cm

  2.  10.9 cm

Step-by-step explanation:

1. You know the legs of a right triangle must be shorter than the hypotenuse. The only answer choice shorter than 8 cm is 7.1 cm.

__

2. By the Law of Sines, ...

  AB/AC = sin(ACB)/sin(B)

  AB = AC·sin(72°)/sin(38°) = 1.545·AC

The approximate value of AC from problem 1 is sufficient to get you close to the answer.

  AB ≈ 7.1×1.545 ≈ 10.9 . . . cm

lord [1]

Answer:

Interest = $1.75

Step-by-step explanation:

Maria invest $600, and receives interest of $30 per year

We know that PRT/100= INTEREST

R=( 100*INTEREST)/(PT)

R = (100*30)/(600*1)

R= 3000/600

R= 5%

Jane invest $350 at Sam rate with Maria , that is 5% , for a year, her interest

Interest= 350*5*1/100

Interest = $1.75

I need help with this question I’m stick
bonufazy [111]

Answer:

4.8 (you can check but that's what I got)

Step-by-step explanation:

First find the missing angle by subtracting the sum of the two given from 180°

180-(47+90) =43°

Then use the Law of Sines to find the missing side

x/sinC = a/sinA

x/sin(90°)/3.5/sin(47°)

x=sin(90°)×(3.5/sin(47°))

x=4.7856...

x ≈ 4.8
