These triangles are congruent by the triangle congruence postulate [?]
Vinvika [58]

Given:

A figure of two congruent triangles.

To find:

The triangle congruence postulate by which the given triangles are congruent.

Solution:

First label the vertices as shown below.

In triangle ABC and triangle CDA,

AB\cong CD                   (Given)

\angle BAC\cong \angle DCA                   (Given)

AC\cong AC                  (Common side)

The corresponding two sides and their included angle are congruent in both triangles. So, triangles are congruent by SAS congruence postulate.

\Delta ABC\cong \Delta CDA            [SAS congruence postulate]

Therefore, the correct option is B.

How do i find the first term of a geometric sequence when i know a3= 1/8 and a6= 1 ?
ale4655 [162]

Answer:

Step-by-step explanation:

nth term = ar^(n-1)

a3 = 1/8;   ar² = 1/8

a6 = 1;      ar⁵ = 1

ar^{2}*r^{3}=1\\\\\frac{1}{8}*r^{3}=1\\\\r^{3}=1*8\\\\r^{3}=8\\\\r^{3}=2^{3}\\\\r=2

ar^{2}=\frac{1}{8}\\\\a*2^{2}=\frac{1}{8}\\\\a*4=\frac{1}{8}\\\\a=\frac{1}{8*4}\\\\a=\frac{1}{32}\\\\
