Answer:
m<MON = 100°
Explanation:
Given:
Area of shaded sector LOM = 2π cm²
NL = 6 cm
Required:
m<MON
Solution:
m<MON = 180° - m<LOM (angles in a straight line)
We don't know m<LOM. Therefore, let's find m<LOM.
Area of a sector = θ/360 × πr²
Area of sector LOM = 2π cm²
r = 3 cm
θ = m<LOM = ?
Plug in the values
2π = m<LOM/360 × π × 3²
2π = m<LOM/360 × 9π
2π = m<LOM × 9π/360
2π = m<LOM × π/40
Multiply both sides by 40
2π × 40 = m<LOM × π
80π = m<LOM × π
Divide both sides by π
80π/π = m<LOM
80 = m<LOM
m<LOM = 80°
✔️m<MON = 180° - m<LOM (angles in a straight line)
Substitute
m<MON = 180° - 80°
m<MON = 100°

Answer:
If the question is (2/3x) = -10,
x = -(1/15) = - 0.06667
The check is presented under the explanation below
If the correct question is (2/3)x = -10,
x = -15
The check is presented under the explanation below
Explanation:
If the question is rightly written as it is in the attached document,
(2/3x) = -10
We can cross multiply and obtain
2 = -10 × 3x
-30x = 2
x = -(2/30) = -(1/15) = - 0.06667
To check
(2/3x) = -10,
(2 ÷ 3x) = -10
2 ÷ 3(-1/15) = 2 ÷ (-1/5) = 2 ÷ (-0.2) = -10 (Correct!)
If the correct question is
(2/3)x = -10
Divide both sides by (2/3)
x = -10 ÷ (2/3)
x = -10 × (3/2)
x = -15
To check
(2/3)x = -10
If x = -15
(2/3) × (-15) = -10 (Correct!)
Hope this Helps!!!
