Which statement about this figure is true. 1 It has no reflection symmetry 2 it has point symmetry. 3 It has reflectional symmetry with one line of symmetry .4 it has rotational symmetry with an angle of rotation of 45

3. Reflection symmetry with one line of symmetry

Step-by-step explanation:

It is a reflection symmetry with one line of symmetry going through the centre.

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
