Ответ:
x = 63, y = 27
Step-by-step explanation:
x and 117 are adjacent angles and sum to 180°
x + 117 = 180 ( subtract 117 from 180 )
x = 63
x and y sum to 90°
x + y = 90
63 + y = 90 ( subtract 63 from both sides )
y = 27
Ответ:
x=63 y= 27
Step-by-step explanation:
180-117=63
x+y=90
63+y=90
90-63 = 27
hope this helps :)
