Answer:
118°
Step-by-step explanation:
Because angle α and the angle that is 62° are a linear pair, that means their added angle measures are equivalent to 180°.
<u>So, to find the missing angle, subtract the known angle from 180:</u>
180 - 62 = a
118 = a
a = 118°
Isaiah can take the divisor and then multiply it by the quotient. If the product is the dividend his answer is correct.
The arc length can be found using the formula, ∅ × r, which is: (5π)/3.
<h3>What is the Arc Length?</h3>
Arc length = ∅ × r, where ∅ is the central angle in radians, and r is the radius of the circle.
Given the following:
- ∅ = 60° = 60° × π/180 (in radians)
- r = 5 cm
Length of the arc = 60° × π/180 × 5 = (60 × π × 5)/180
Length of the arc = (300π)/180 = (5π)/3

Answer:
B. 1.82n
Step-by-step explanation:
Expression given: n + n - 0.18n
Adding n+n gives '2n'
then subtracting 0.18n from 2n gives= 1.82 n
Therefore,
n + n - 0.18n=0.18n
