Answer:

arc BC: 8.55 cm
chord BC: 8.03 cm

Step-by-step explanation:

The length of an arc that subtends central angle α will be ...

s = rα . . . . where α is in radians

The central angle BOC is twice the measure of angle QBC, so is 70°, or 7π/18 radians. So, the length of arc BC is ...

s = (7 cm)(7π/18) ≈ 8.55 cm . . . arc BC

For central angle α and radius r, the chord subtending the arc is ...

c = 2r·sin(α/2)

c = 2(7 cm)sin(35°) ≈ 8.03 cm . . . . chord AB

Angle C and angle D are supplementary. If the measure of angle D is 84 degrees, what is the measure

garik1379 [7]

Suplementary is angles add up to 180 degrees

C=180-D

C=180-84

C=96 degrees

Hope this helped :)

Find the solutions to x² = 12.

Novosadov [1.4K]

Answer:

$x = \pm 2\sqrt3$

Step-by-step explanation:

Hello!

Let's use the square root property to solve this question

Solve:

$x^2 = 12$
$\sqrt{x^2} = \sqrt{12}$
$x = \pm\sqrt{12}$
$x = \pm \sqrt{4 * 3}$
$x = \pm 2\sqrt3$

The answer is option A: x = ±2√3
