Answer:

b = 115.4 feet

Step-by-step explanation:

b^2 = a^2 + c^2 - 2 (a)(b) x cos B

b^2 = 230^2 + 360^2 - 2(230)(360) x cos(38 degrees)

b^2 = 52,900 + 129,600 - 2(230)(360) x cos(38 degrees)

b^2 = 182,500 - 165,600 x cos(38 degrees)

b = $\sqrt{(16,900)(cos(38)) }$

b = 115.4 feet

i hope this helps!! :)

Find the 10th term of the arithmetic sequence with the terms a1=15 and d=80

Alchen [17]

Answer:

The 10th term is 735

Step-by-step explanation:

The 10th term of an <em>Arithmetic Sequence </em>is given by:

$a_{10}=a_1+9d$

From the question, we were given that:

$a_{1}=15$

and

$d = 80$

We substitute these values into the above expresion to obtain:

$a_{10}=15+9 \times 80$

$a_{10}=15+720$

$a_{10} = 735$

Using distributive property

Hoochie [10]

Answer:

Step-by-step: Step 1: Add -19x to both sides

48x-6y+3+-19x=19x+15y+-19x

29x-6y+3=15y

Step 2: Add 6y to both sides

29x-6y+3+6y=15y+6y

29x+3=21y

Step 3: Add -3 to both sides

29x+3+-3=21y+-3

29x=21y-3

Step 4: Divide both sides by 29

29x/29=21y-3/29

x=21/29y+ -3/29
