Answer:
n=-1
Step-by-step explanation:
First you add 5 to both sides an you would get -15n=15
Next divide by -15 on both sides and get n=-1

Answer:
S = 3.92π
Step-by-step explanation:
The formula for area of a sector is
S = (Ф/360°)πr² where Ф is the angle of the sector in degrees, and r is the radius.
The radius is half of the diameter, so we have 5 = 5.6/2 = 2.8, and Ф = 180°
The area is
S = (180°/360°)π(2.8)²
S = (1/2)π(7.84)
S = 3.92π

Step-by-step explanation:
<u>Complete Question</u>: In right triangle XYZ, the right angle is located at vertex Y. The length of line segment XY is 12.4 cm. The length of line segment YZ is 15.1 cm. What is the approximate measure of angle YZX?
Applying trigonometric ratio to right angled triangle XYZ,
tan θ
Calculating for ∠YZX, ∠YZX = θ
tan θ
tan θ = 0.8212
θ = tan⁻¹ 0.8212
θ = 39.39°
θ ≈ 39.4°
