(reposted for points)

Supplementary angles sum up to 180 degrees.

2x - 4 + 2x + 4 = 180

4x = 180

x = 45

Therefore,

m<9 = 2(45) - 4 = 90 - 4 = 86 degrees

m<10 = 2x + 4 = 90 + 4 = 94 degrees.

ABC and AED are straight lines.
grandymaker [24]

Answer:

  • CD = 5.7 cm
  • ED = 3.05 cm

Step-by-step explanation:

a) ΔACD ~ ΔABE so the ratios of corresponding sides are the same. That is ...

  CD/BE = CA/BA

  CD/3.8 = 12.3/8.2

  CD = 3.8×12.3/8.2 = 5.7 . . . . cm

__

b) As above, the ratios of corresponding sides are the same.

  ED/AD = BC/AC

  ED/9.15 = (12.3-8.2)/12.3 . . . . BC = AC - AB

  ED = 9.15×4.1/12.3 = 3.05 . . . . cm

The coordinates of a point on a coordinate grid are (−3, 7). The point is reflected across the x-axis to obtain a new point. The
Semenov [28]

Answer:

"1. (−3, −7)"

Step-by-step explanation:

If we have a point (x,y),

1. Reflection across x axis makes it (x, -y)

2. Reflection across y axis makes it (-x, y)

So we see x-axis reflection simply changes sign of y coordinate & y-axis reflection changes the sign of x coordinate (keeping x and y same, respectively).

Thus, the question asks to reflect (-3,7) about x-axis, so we change sign of y coordinate, 7 becomes -7. THus, the point becomes:

(-3,-7)

Answer choice #1 is right.
