<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
Sorry i don’t know the answer but i’m new to this app, and was wondering what brainliest is?:)
Answer:

Step-by-step explanation:
Slope is negative reciprocal when two lines are perpendicular
m1=1/2 therefore m2=-2
The equation of the line in point-slope form is given as

Here m=-2 and (x1, y1)=(-3, -1)
Therefore,

Answer:
163/20 or 8.15
Step-by-step explanation:
well we are going to do PEMDAS
parentheses
exponents
multiplication/ division
addition/ subtraction
2 + 2/5 x 23/4 (i made the fractions into decimals)
2 + 6.15
163/20 or 8.15
