Answer:
x = 7, x = 5
Step-by-step explanation:
Given 2 intersecting chords, then
The product of the parts of one chord is equal to the product of the parts of the other chord.
(1)
27x = 9 × 21 = 189 ( divide both sides by 27 )
x = 7
(2)
12(3x - 5) = 120 ( divide both sides by 12 )
3x - 5 = 10 ( add 5 to both sides )
3x = 15 ( divide both sides by 3 )
x = 5
Answer:
x = 15°
Step-by-step explanation:
The secant- tangent angle x is half the difference of the intercepted arcs, that is
x =
(80 - 50)° = 0.5 × 30° = 15°
Answer:
9/24
Step-by-step explanation:
3/8
24 ÷ 8 = 3
3 x 3 = 9
9/24
Check:
9/24 = 0.375
3/8 = 0.375
