Question

the sum of the two angles angles is 72 degree and their difference is 20 grade. find the angles in garage

Answer 1

Answer:

Step-by-step explanation:

x+y=72

x-y=20

2x=92

x=46

Answer 2

${\textsf{\textbf{\underline{Given :-}}}}$

the sum of the two angles is 72 degree and their difference is 20 degree

${\textsf{\textbf{\underline{To Find :-}}}}$

Angle

${\textsf{\textbf{\underline{Solution :-}}}}$

Let

∠1 = x

∠2 = y

x + y = 72 (1)

x - y = 20 (2)

On adding both

x + y + x - y = 72 + 20

2x = 92

x = 92/2

x = 46

Using 1

46 + y = 72

y = 72 - 46

y = 26
