Letter B is not true.
You have to follow the ORDER of the congruence statement to be sure the angle in the middle of each statement lines up with each triangle.

Answer:

196608

Step-by-step explanation:

3, -12, 48, -192, ... is a geometric sequence with first term 3 and common ratio -4. Note that (-12)(-4) = 48, that (48)(-4) = -192, and so on. The general formula for a geom. seq. is a(n) = a(1)r^(n-1), where a(1) is the first term and r is the common ratio. In this particular case, we have

a(n) = 3*(-4)^(9-1) = 3*(-4)^8 = 3(65536) = 196608

X-1/34=16/17 solve for x

In-s [12.5K]

Answer:

$x - \frac{1}{34} = \frac{16}{17} \\ x = \frac{16}{17} + \frac{1}{34} \\ x = \frac{32}{34} + \frac{1}{34} \\ x = \frac{33}{34}$

Name two different ways to construct congruent angles

Norma-Jean [14]

A first way is considering opposite angles:

Pick a point, $O$
Draw two rays $r,s$ starting from $O$
Let $\alpha$ be the angle between $r$ and $s$
Elongate both $r$ and $s$ with respect to $O$ to obtain the rays $r'$ and $s'$
The angle between $r'$ and $s'$ is also $\alpha$

Alternatively, you can start with a given angle, and then draw its bisector. By definition, the bisector cuts a given angle in two equal parts, so you divide an angle $\alpha$ in two parts, both measuring $\frac{\alpha}{2}$
