Question 1079062
if two angles in the ratio of 5:4 are represented by 5x and 4x express each of the following statements as an equation
a)the angles are adjacent and together form an angle measuring 45degrees
b)the angles are complementary 
c)the angles are supplemetary
d)the angles are two angles of a triangle whose third angle is their difference
solution 
let angle are 5x and 4x 
a) sum is 45 degree 
5x+4x=45
9x=45
x=5 angle are 5x=25 and 4x=20 degree 
b)angle are complimentary 
5x+4x=90
9x=90
x=10 degree   angle are 50 and 40 degree 
c)angle are supplementary  means 5x+4X=180
9x =180
x=20 degree angles are 100 and 80 degree 
d)third angle is difference =5x-4x=x 
5x+4x+x=180 angle sum property of triangle 
10x=180
x=18 degree agle are 90 ,72,18 degree 
total sum will be 180
