Please help find them <br>1 AB<br><br>2 BC​
spin [16.1K]

Answer:

AB ≈ 15.7 cm, BC ≈ 18.7 cm

Step-by-step explanation:

(1)

Using the Cosine rule in Δ ABD

AB² = 12.4² + 16.5² - (2 × 12.4 × 16.5 × cos64° )

       = 153.76 + 272.25 - (409.2 cos64° )

       = 426.01 - 179.38

       = 246.63 ( take the square root of both sides )

AB = \sqrt{246.63} ≈ 15.7 cm ( to 1 dec. place )

(2)

Calculate ∠ BCD in Δ BCD

∠ BCD = 180° - (53 +  95)° ← angle sum in triangle

∠ BCD = 180° - 148° = 32°

Using the Sine rule in Δ BCD

\frac{BC}{sin53} = \frac{BD}{sin32} = \frac{12.4}{sin32} ( cross- multiply )

BC × sin32° = 12.4 × sin53° ( divide both sides by sin32° )

BC = \frac{12.4sin53}{sin32} ≈ 18.7 cm ( to 1 dec. place )

Write the equation in standard form for the circle with center (0, -6) and radius 7.
LUCKY_DIMON [66]

Step-by-step explanation:

the equation of circle is given by

(x - h) {}^{2} + (y - k) {}^{2}  =  {r}^{2}  \\ (x - 0) {}^{2}  +  {(y + 6)}^{2}  =  {7}^{2}  \\  {x }^{2}  +  {y}^{2}  + 12y + 36 = 49 \\  {x  }^{2}  +  {y}^{2}  + 12y = 13
