Answer:
<2 and <3
Step-by-step explanation:
Given that lines l and m are parallel to each other, and crossed by the transversal line t, the angles formed that are supplementary to <1 are <2 and <3.
<1 and <2 are linear pair. Their sum equal 180°.
<1 and <2 are also a linear pair. Their sum equal 180°.
Therefore, that are supplementary to <1 are <2 and <3.
Answer:
x = 5/4 + √65/4 or x = 5/4 - √65/4
Step-by-step explanation:
I'm assuming you mean 2x^2-5x-5=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 = 5/4 ± √65/4
Therefore, x = 5/4 + √65/4 or x = 5/4 - √65/4
