Complementary angles are those angles whose sum is 90 degree.
The measurement of two complementary angles are
There sum have to be 90 degree. That is
Combining like terms ,
Moving 20 to right side
Dividing both sides by 5
So the measurement of the angles are
But what are we meant to unscramble?
By the way, if you haven’t noticed this is maths not english
8x16=? 6x12=? Then add both answers ?+?=?
4(5x-20)=-20
20x-80=-20
20x=60
x=3
Answer:
Step-by-step explanation:
3n+15=75
three times a number is 3n. +15 is 15 more.
3n+15=75 subtract 15 from both sides to get the 3n alone
3n=60 divide by 3 to get the n by itself
n=20
