<h2>
Answer:</h2>
<h3>
<em>x=45degrees</em></h3>
<h2>
Step-by-step explanation:</h2>
Let the angle to be solved be x
Let the supplement/compliment by y
x+y=90 Complimentary angles add up to 90 degrees.
x+3y=180 Supplementary angles add up to 180 degrees, the other angle is thrice the other compliment.
Evaluating this as a system:
x+y=90 Isolate x:
x=90−y Input into the other equation:
(90−y)+3y=180 Combine like terms, isolate y and its coefficients:
2y=90 Isolate y
y=45 Input into the first equation:
x+45=90 Isolate x:
x=45degrees
take it and leave it somewhere u will forget about it and move on with ur life lol
Next, solve as you would solve any two-step inequality. Since 2 is added to , you can get by itself on one side of the inequality by subtracting 2 from both sides. Then, to get by itself on one side of the inequality, you need to multiply both sides by 2.D
The value of 
in the first quadrant is approximately 0.173.
There are 4 quadrants inside the cartesian aircraft. All trigonometric ratios of sin, cos, tan are high quality inside the first quadrant.in the 2nd quadrant simplest sin is advantageous rest are negative. within the 1/3 quadrant simplest tan is wonderful inside the fourth quadrant best cos is fantastic.
Given 
and 
is in the first quadrant.
We know from trigonometrical identities that
Substituting the value of 
in the above equation we get:
As lies in the first quadrant then the value of 
is positive.
∴
From the properties of trigonometry we know that :
The value of is approximately 0.173 to the nearest thousandth . The value is positive as the angle lies in the first quadrant.
