Question 214848This question is from textbook Geometry for Enjoyment and Challenge

: i'm having trouble finding m<1 . . .
Given:
<1 and <2 are supplementary
<2 and <3 are supplementary
<1= x^2+3y
<2= 20y+3
<3= 3y+4x
Find: m<1
(does not require proof)
i've found x= -5.75+44.25, but i am confused on how to proceed ? how would you solve (-5.75+44.25)^2+3y+20y+3=180 ?
please help, thank you !!

Question 215117: One of two complementary angles is ywo more than one third of the other. Find the two angles.
I set up the equation as 90=x+(1/3x)+2 and proceeded to solve but i got x as equalling 132. This cant be right since complementary angles only can equal 90.
