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

we have

substitute the values

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

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
Step-by-step explanation:
First determine how much he made using an estimate
Earnings = hours * rate per hour We estimate 40 hours * 10 per hour
= 40 * 10
=400
Take home after taxes is 4/5 of his earnings
take home = 4/5 * 400
=320
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
