Given that R= 9x + 8y<br> Find y when x = 3 and R= 27

Amiraneli [1.4K]

Answer:

1/3 or 0.3 (recurring)

Step-by-step explanation:

Let's substitute our numbers into the equation.

27 = 9x + 24 I multipled 8 by 3 in order to get 24, because x equals 3.

Now take away 24 leaving 9x on its own.

3 = 9x

Divide 9 to separate it from x.

3/9 = x

Simplify the fraction.

1/3 = x

Solve the triangle. Round your answers to the nearest tenth.

Rasek [7]

Answer:

m∠A ≈ 43°

m∠B ≈ 55°

mBC ≈ 20

Step-by-step explanation:

Law of Sines: $\frac{a}{sinA} =\frac{b}{sinB} =\frac{c}{sinC}$

Step 1: Find m∠B

$\frac{29}{sin82} =\frac{24}{sinB}$

Step 2: Solve for ∠B

29sinB = 24sin82°

sinB = 24sin82°/29

B = sin⁻¹(24sin82°/29)

B = 55.038°

Step 3: Find m∠A

180 - (55.038 + 82)

180 - 137.038

m∠A = 42.962°

Step 4: Find BC

$\frac{29}{sin82} =\frac{BC}{sin42.962}$

Step 5: Solve for BC

29sin42.962° = BCsin82°

BC = 29sin42.962°/sin82°

BC = 19.9581
