Answer:
C. 18 cm
Step-by-step explanation:
The ratio of the sides of the triangle shown is 12 : 15 = 4 : 5. We know it is a right triangle, so we know the missing side length completes the ratio
3 : 4 : 5 = 9 : 12 : 15
Half of XY is 9 cm, so the length of the entire chord is 18 cm.
_____
The chord is tangent to the inner circle, so makes a 90° angle with the radius to that tangent point. This tells you that the triangle shown is a right triangle. It also tells you that the short radius bisects the chord. The Pythagorean theorem can be used to find the length of the side not shown (half the chord length).
The unknown side (a) can be found from ...
15² = 12² +a²
225 -144 = a² . . . . . . subtract 12²
81 = a² . . . . . . . . . . . simplify
9 = a . . . . . . . . . . . . . take the square root
The chord length is 2a, so is ...
2(9 cm) = 18 cm . . . . length of chord XY
Answer:
Triangle in isosceles, scalene or equilateral forms and
quadrilateral in trapezoid, rectangle or square forms
Step-by-step explanation:
<em>Refer to pictures attached</em>
<u>Shapes can be formed are:</u>
<em>when perpendicular to base</em>
- Rectangle or square<em>,</em>
<em>when angle cross section to base</em>
when base is isosceles triangle and parallel cross section to base,
or angle cross section
<em>when base is scalene triangle and parallel cross section to base,</em>
<em>or angle cross section</em>
<em>when base is equilateral triangle and parallel cross section to base,</em>
<em>or angle cross section</em>
The correct answer is <u><em>B. 105/3</em></u>
