Answer: Option A; cos(28°) = 15/17

Step-by-step explanation:

You must remember that for a triangle rectangle we have that:

Sin( angle) = (opposite cathetus)/hypotenuse

cos(angle) = (adjacent cathetus)/hypotenuse

tan(angle) = (opposite cathetus)/(adjacent cathetus)

We want to find the cos(28°), then we can use the second relation, where the adjacent cathetus is 15 units long, and the hypotenuse is 17 units.

cos(28°) = 15/17

Then the correct option is A.

If a diameter intersects a chord of a circle at a perpendicular, what conclusion can be made?
Agata [3.3K]

If a diameter intersects a chord of a circle at a perpendicular then the chord is bisected.

<h3>What is the relation between the chord and diameter of a circle?</h3>
  • The segments of a circle whose endpoints are on its perimeter are called chords.
  • A circle's diameter is the chord that passes across its center.
  • The circle's longest chord equals its diameter.
  • Any line that is perpendicular to a chord on the circle cuts it in half and goes through the center.

The solution to the problem:

A circle's chord is intersected perpendicularly by its diameter, which also passes through the center of the circle. The chord and diameter are perpendicular. Any line that is perpendicular to a chord on the circle and passes through its center divides it. The chord is divided equally by the diameter.

Therefore, the chord is bisected.

I 5 The sum 1 + 9 + 3 + 3 + i + 2 gives the amount of mix. 1+ 2+ 3+3+1+1
SVETLANKA909090 [29]

Answer:

i = -7

Step-by-step explanation:

1) Set up equation

1+9+3+3+i+2 = 1+2+3+3+1+1

2) Combine like terms

18+i = 11

3) Factor out for the answer

18+i = 11

18-18+i = 11-18

i = -7

Hopefully this helps you!
