I need the answers to questions 1&2
Leokris [45]

Answer:

see explanation

Step-by-step explanation:

(1)

the sine of an angle = \frac{opposite}{hypotenuse}

(a)

here the opposite is 12 and the hypotenuse is 13

12 is the side opposite ∠DEF ← required angle

(b)

the tangent of an angle = \frac{opposite}{adjacent}

here the opposite is 5 and the adjacent is 12

∠DFE ← required angle

(2)

to calculate AB use Pythagoras' identity in the right triangle

AB² = 2² + 3² = 4 + 9 = 13, hence

AB = \sqrt{13} ≈ 3.6 ( to nearest tenth )

tanB = \frac{2}{3} ⇒ B = 33.7°

tanA = \frac{3}{2} ⇒ A = 56.3°

Given the measure of an interior angle of a regular polygon, how many sides does the polygon have?
Elis [28]

The sides of a regular polygon with a known interior angles can be found as follows:

Interior Angle = (n−2) × 180° / n

<h3 /><h3 /><h3>Regular polygon</h3>

A regular polygon is a polygon that have equal sides and equal angles.

A regular polygon has the following angles:

  • interior angles
  • exterior angles

According to the question, the interior angles are given. To know the number of sides of polygon can be calculated as follows:

Note the interior and the exterior angles add up to 180 degrees.

Therefore,

Interior Angle = 180° − Exterior Angle

Exterior angle = 360°/n

Interior Angle = 180° − 360°/n

n = number of sides

Finally,

  • Interior angle = (n−2) × 180° / n
