In order for l and m to be parallel, x° must be the supplement to the sum of 50° and 55°.
x° = 180° -50° -55°
x° = 75°
The 1st choice is appropriate.
Answer:
use an online calculator is the best option
Step-by-step explanation:
Tanx-5=0
tanx=5
tan inverse (5)=x
78.69
Theta = 210°
r = 4.6/2 = 2.3
Area of circle = pi * r * r
= 3.14 * 2.3 * 2.3 = 16.61
Area of sector =
(theta / 360) * area of circle
= (210/360) * 16.61
= 9.69
Answer:
<h3>sum of 5 times of x and thrice of y is 106</h3>
