What is the angle measure of the third angle of a triangle given the two angles below? 59 degrees and 58 degrees

firstly a triangle has angle sum of 180°

Step-by-step explanation:

let all the three angles be x,y and z such that x+y+z =180°

let x= 58° and y =59°

the to calculate for the unknown z angle ;

make z subject of the formula

thus z= 180° -x-y

> z= (180-58-59)°

z= 180-117

z= 63°

y=x+9

?
