The measure of the supplement of an angle is 46 more than 3 times the complement of the angle. Find the angle.

A) angle =22
B) angle =68
C) angle =112
D) angle =44

45 degrees

Step-by-step explanation:

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+3

y=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=180Combine like terms, isolate y and its coefficients:2y=90 Isolate yy=45 Input into the first equation:x+45=90 Isolate x:x=45 degrees

step-by-step explanation: a reaction is first order. if the initial reactant concentration is 0.0200 m, and 25.0 days later the concentration is 6.25 x 10-4 m, then its half-life is:
