Answer:

Step-by-step explanation:

Sum of all angles of triangle = 180

39 + 102 + x = 180

141 + x = 180

Subtract 141 from both sides

x = 180 - 141

x = 39

Dan saved twice as much as Brett. Maria saved $60 more than Brett. If they saved $600 altogether, how much did Maria save?

givi [52]

Setting it up, we have Dan + Bret + Maria all saving 600.00
Dan = 2B
Bret = B
Maria = B+60

2B + B + B + 60 = 600
4B = 540
B = 135

Dan = 2(135) = 270
Brett = 135
Maria = 135 + 60 = 195

Sunny_sXe [5.5K]

Reflection involves mirroring a point over a line.

<em>When L is reflected across the x and y axes, the new coordinates are (7,3)</em>

Given that:

$(x,y) \to (-7,-3)$

When a point is reflected across the x-axis, the rule is:

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

So, we have:

$(-7,-3) \to (-7,3)$

When a point is reflected across the y-axis, the rule is:

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

So, we have:

$(-7,3) \to (7,3)$

Hence, the new coordinates of L are (7,3)
