Answer:

1) 102

2) x = 31°; y = 6

3) m = 28°, n = 31°

4) x = 79°

Step-by-step explanation:

1) Angle ABD = 180 - 2(69) = 42

Angle DBC = 180/3 = 60

Angle ABC = 42 + 60 = 102

2) Angle ABC = 180 - 2(59) = 62

x = 62/2

x = 31°

ABD and CBD are congruent triangles so y = 6

3) 118 = m + 90

Exterior angle = sum of interior angles

m = 118 - 90 = 28°

n = (180-118)/2 = 31°

4) x = (180-22)/2 = 79°

___ x 4 = 12<br> ___ x 5 = 20<br> ___ x 2 = 10

RideAnS [48]

Answer:

3 x 4 = 12

4 x 5 = 20

5 x 2 = 10

Step-by-step explanation:

3 + 3 + 3 + 3 = 12

3 four times equals 12

This is the same for the others

4 + 4 + 4 + 4 + 4 = 20

Describe a sequence of transformations that transform the graph of the parent function f into the graph of the function g.

olganol [36]

Answer:

The sequence is: Refection across y-axis, Horizontal Shrink, Horizontal Translation and Reflection across x-axis.

Step-by-step explanation:

Since, we are given f(x) = square root x.

The sequence of transformations which transform f(x) into g(x) is given by:

1. Reflection across y-axis i.e. f( x ) to f( -x )

2. Horizontal Shrinking i.e. f( -x ) to f( -x/2 )

3. Horizontal Translation i.e. f( -x/2 ) to f( -x/2 + 3 )

4. Reflection across x-axis i.e. f( -x/2 + 3 ) to -f( -x/2 + 3).
