pentagon [3]

<em>Two </em>or <u>more</u> triangles are said to be congruent if and only if they have <u>equal</u> lengths of <em>sides</em> and <u>equal</u> measures of <em>angles</em>.

Thus, the required <u>proof</u> is as shown below:

   <u>STATEMENTS </u>                                             <u>REASONS</u>

1. ΔABC and ΔDEC with AB ≅ DE;

  BC ≅ EC; <1 ≅ <2                                          Given

2. <1 and < ABC; < 2 and <DEC are sup     <u>Sum</u> of angles on a <em>straight </em>line

3. <ABC ≅ <DEC                                <em>Congruent</em> angles of <u>similar</u> triangles

4. ∴ΔABC ≅ ΔDEC                              <em>Side-Angle-Side</em> (SAS) postulate

5. ∴<ACB ≅ <DCE                                         CPCTC postulate

<h3>Answer: Choice B</h3>

Angle 1 = 147 degrees

Angle 2 = 80 degrees

Angle 3 = 148 degrees

======================================================

Work Shown:

(angle 1) + 33 = 180

angle 1 = 180-33

angle 1 = 147 degrees

---------------

Focus on the left most triangle that has angles 33 and 47 as interior angles. The missing angle is 180-33-47 = 100 degrees

The angle exterior to this 100 degree angle is angle 2

angle 2 = 180-100 = 80

We have enough info to conclude the answer must be choice B.

---------------

Let's keep going to find angle 3

The vertical angle for the 100 degree angle is also 100 degrees. This second 100 degree angle is part of the triangle on the right

This triangle on the right has interior angles 100 and 48

The missing interior angle is 180-100-48 = 32

The angle supplementary to this is 180-32 = 148, which is angle 3.

1) 2x11 =<br> I don’t know how to do this
Fynjy0 [20]

Answer:

22, Twenty Two

Step-by-step explanation:

A good way to look at multiplying 11 is that the number, if it’s under 10, will then be two of that number. For instance, 4 x 11 = 44, 6 x 11 = 66, and so on and so forth.

Hope This Helped!

Which equation can be used to find the solution of (1/2)y+1=64?
Alex17521 [72]

Answer: y = 126

<u>Explanation:</u>

\frac{1}{2}y + 1 = 64

 <u>     -1 </u>     <u>-1  </u>

\frac{1}{2}y = 63

(2)\frac{1}{2}y = 63(2)

 y = 126
