Answer:
Step-by-step explanation:
The first angle us (61x+3)
The second angle is (25x+5)
We use corresponding angles to get the top angle as a linear pair to (25x+5).
We use sum of angles on a straight line to obtain:
Group similar terms
We substitute to get:
Answer:
Diameter = 9
Step-by-step explanation:
Let the diameter be represented as x.
Based on the secant-tangent theorem, the following equation representing the relationship between the segments would be:
(16 + x)(16) = 20²
256 + 16x = 400
Subtract 256 from each side
16x = 400 - 256
16x = 144
Divide both sides by 16
x = 144/16
x = 9
Diameter = 9

Answer:
3
Step-by-step explanation:
6x - 2x + 12 - 8x = 6x + 6 / 10
= 4x + 12 - 8x = 6x + 6 / 10
= 120 - 40x = 6x + 6
= 120 - 40x - 6x - 6
= - 46x = -114
= x = 114 / 46
= 2.47 ~~ 3.
