Answer:
Step-by-step explanation:
The line BD divides a right angle into two acute angles <CBD + <DBA
They add to 90.
They are therefore complementary.
The word you are looking for is complementary.
Answer:
1 6/7
Step-by-step explanation:
1 & 6/7
Answer: O 3-7,5, 18, 24, 32}
O {-9, 7, 15, 22, 26}
these two sets are not equal
Add 3 to both sides so that the equation becomes -2x^2 + 5x + 5 = 0.
To find the solutions to this equation, we can apply the quadratic formula. This quadratic formula solves equations of the form ax^2 + bx + c = 0
x = [ -b ± √(b^2 - 4ac) ] / (2a)
x = [ -5 ± √(5^2 - 4(-2)(5)) ] / ( 2(-2) )
x = [-5 ± √(25 - (-40) ) ] / ( -4 )
x = [-5 ± √(65) ] / ( -4)
x = [-5 ± sqrt(65) ] / ( -4 )
x = 5/4 ± -sqrt(65)/4
The answers are 5/4 + sqrt(65)/4 and 5/4 - sqrt(65)/4..
