Line segment KL is tangent to circle J at point K.
Shalnov [3]

we know that

if the line segment KL is tangent to circle J at point K

then

KL is perpendicular to KJ

the triangle KJL is a right triangle

Applying the Pythagorean Theorem

LJ^{2} =KL^{2}+KJ^{2}

we have

KL=24\ units\\KJ=r\ units\\JL=(16+r)\ units

substitute the values

(16+r)^{2} =24^{2}+r^{2}\\256+32r+ r^{2}=576+ r^{2} \\32r=576-256 \\r= 320/32\\r=10\ units

therefore

<u>the answer is the option B</u>

10\ units

Answer:

A = 26.6°

Step-by-step explanation:

To obtain the measure of angle A :

We use the trigonometric relation :

Tan A = opposite / Adjacent

Tan A = 6 / 12

Tan A = 1/2

A = tan^-1(1/2)

A = 26.565°

A = 26.6°

Answer:

13.  $320

The perimeter of an isosceles triangle is 24cm. The unequal side is twice as long as the equal sides.
Rufina [12.5K]

Answer:

Equal sides = 6cm each

Unequal side = 12cm

Step-by-step explanation:

Perimeter of a triangle = side a + side b + side c

Let

Side a = side b = x

Side c = 2x

Perimeter of the triangle=24cm

Perimeter of a triangle = side a + side b + side c

24 = x + x + 2x

24 = 4x

Divide both sides by 4

24 / 4 = 4x / 4

6 = x

x = 6

The equal sides = x = 6cm each

The unequal side = 2x

= 2(6)

= 12cm

Check:

Perimeter of a triangle = side a + side b + side c

= 6cm + 6cm + 12cm

= 24cm
