One angle is 5 degrees less than three times the degree measure of another angle. Together the angles measures have a sum of 143. What is the measure of each angle.

Another angle = 37° and First angle = 3(37)-5 = 106°

Step-by-step explanation:

Let the measure of another angle is x°.

First angle is 5 degrees less than three times the degree measure of another angle = 3x-5

Together the measures of angles have a sum of 143.

ATQ,

x+3x-5 = 143

Taking like terms together,

x+3x = 143+5

4x = 148

x = 37

Another angle = 37°

First angle = 3(37)-5 = 106°

Hence, this is the required solution.

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice

p.s.   i'll be on vacation from friday, dec 22 to jan 2, 2019. have a great new year!
