Question

If the sum and difference of two angles of a triangle are 124 degrees and 36 degrees respectively, find the measure of each angle of the triangle

Answer 1

Answer:

first angle=80

second angle= 44

third angle= 180-(80+44)=56

Step-by-step explanation:

Hi friend.

this is how I solve it.

x = the first angle

y= the second angle

x+y = 124

x-y= 36

x+y-(x-y)= 124-36

= x+y-x+y= 88

=2 y= 88 , y=44

------> x=80

Answer 2

Answer:

Let 2 angles be x and y

According to first condition,

X + Y = 124 - - - - (1)

According to second condition,

X - Y = 36 - - - - (2)

Add equation 1 and 2

2x =160

X =80

Put x = 80 in equation 2

-y=36 - 80

Y =44
