Answer:
x =
Step-by-step explanation:
Given 2 intersecting chords in a circle, then
The product of the parts of 1 chord is equal to the product of the parts of the other chord, that is
6x = 7 × 13 = 91 ( divide both sides by 6 )
x =
The correct answer is, b=4.
Given Information and To Find
It is given that in a right angled-triangle lmn,
∠m = 90°
∠l = x°
ln = 20 units
lm = 3b units
We have to find the value of b.
What is a right-angled triangle?
A right triangle is a triangle in which one of the angles is at a right angle or two of the sides are perpendicular, or more formally, an orthogonal triangle, formerly known as a right-angled triangle. Trigonometry's fundamental concept is the relationship between a right triangle's sides and other angles.
Applying Trigonometry
We know that in a right angled-triangle,
In this case, we have (refer to the diagram),

Answer:
After the tip you would leave $43.20
Step-by-step explanation:
In order to find this, we must first find 20% of 36. In order to do that, you must multiply them together (don't forget to turn the percentage into a decimal first).
36 * .20 = 7.20
Now we can add the total amount pre-tip and the tip amount to find the overall total.
$36 + $7.20 = $43.20
The answer would be D. hope this helps :))
