Two complementary angles = 90°
X = 18+ 2y
X + y = 90
Plug first equation into second
18 + 2y +y = 90
18 + 3y = 90
18 – 18 +3y = 90 – 18
3 y = 72
3y/3 = 72/3
Y = 24
Plug y into 2nd formula
X + 24 = 90
X + 24 -24 = 90 – 24
X = 66

Plz give me correct answers ​
son4ous [18]

Answer:

Addition = 3656999

Step-by-step explanation:

Predecessor of number = (Number - 1)

Predecessor of 365000 = 365000 - 1

                                         = 364999

Successor of a number = (Number + 1)

Successor of 3291999 = 3291999 + 1

                                      = 3292000

Now we have have to add the predecessor of 365000 and successor of 3291999,

364999 + 3292000 = 3656999

In other words addition of predecessor of any number and successor of other number will be same as the sum of both the numbers.
