It would be 56 degrees since it's a vertical angle and to get the obtuse angles you just subtract 180 from 56 and there's your answer. Hope this helped! (':

The vertices of ABC are A(-3,5), B(-2,3), and C(-5,3). If ABC is reflected across the y-axis to produce the image A'B'C', find t

Nat2105 [25]

Answer:

$C' =(5,3)$

Step-by-step explanation:

Given

$A = (-3,5)$

$B = (-2,3)$

$C = (-5,3)$

Reflection across y-axis

Required

Find C'

For reflection across y-axis, the rule is:

$(x,y) \to (-x,y)$

So, the image of C is:

$(-5,3) \to (-(-5),3)$

$(-5,3) \to (5,3)$

Hence:

$C' =(5,3)$

-2 4/5 + 1/4 equals what ?

vlada-n [284]

Hey there! :)

Since 2 4/5 is greater than 1/4, the answer is negative.

You can just subtract 2 4/5 and 1/4 and add the (-) sign

2 4/5 - 1/4

Change the fractions so they can have a common denominator: 20

2 4/5 = 2 16/20

1/4 = 5/20

2 16/20 - 5/20 = 2 11/20

Add the (-) sign → -2 11/20

Answer ⇒ -2 11/20
