Vsevolod [243]

Given:

Measure of arc FJ = 84°

Measure of arc GH = 76°

To find:

The measure of angle HKJ.

Solution:

The image of the question is attached below.

Angles inside the circle theorem:

If two chords intersect inside a circle, then the measure of each angle is one half the sum of the measures of the intercepted arc and its vertical arc.

$\Rightarrow m \angle G K H=\frac{1}{2}(m(a r  \ G H)+m(a r \  F J))

$\Rightarrow m \angle G K H=\frac{1}{2}\left(76^{\circ}+84^{\circ}\right)

$\Rightarrow m \angle G K H=\frac{1}{2}\left(160^{\circ}\right)

\Rightarrow m \angle G K H=80^{\circ}

Sum of the adjacent angles in a straight line is 180°.

⇒ m∠GKH + m∠HKJ = 180°

⇒ 80° + m∠HKJ = 180°

Subtract 80° from both sides.

⇒ 80° + m∠HKJ - 80° = 180° - 80°

⇒ m∠HKJ = 100°

The measure of ∠HKJ is 100°.

I NEED HELP WITH TRIGONOMETRY !!
shutvik [7]

x is 14.3

\frac{x}{ \sin(a) } =  \frac{y}{ \sin(b) }

the right angle is 90 degrees, so sin(a) is 90

\frac{x}{ \sin(90) }  =  \frac{9}{ \sin(39) }

multiply sin(90) on both sides to give:

x =  \frac{9}{ \sin(39) }  \times  \sin(90)

x is 14.3
