Can someone please help me with this two please

1. B

2. C

Step-by-step explanation:

1. In this, we already know one side and one angle are congruent. For the triangles to be congruent by SAS, another side is necessary. Thus CB = FE

2. Here, we see that one set of sides are congruent. We see another set of angles are congruent as well. We also know that the center angle is congruent as the angles are formed by two straight lines intersecting. Since we  see 2 next door angles and the side beside it congruent, they are proven congruent by AAS.

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents

x=half
