What is the angle of c in the above equilateral triangle?

Answers

First remember what all the angles in a triangle add up to (which is 180) and since it is an equilateral triangle, divide by 3. Your answer will be 60.

Help please I really need to solve for x

Answers

[tex](6 - 2) \times 180 = 4 \times 180 = 720 \\ [/tex]

So the sum of the nterior angles of the figure must equal 720° :

[tex](x - 8) + 4x + 2x + 3x + 2x + 2x = 720 \\ [/tex]

[tex]14x - 8 = 720[/tex]

Plus both sides 8

[tex]14x = 728[/tex]

Divided both sides by 14

[tex]x = \frac{728}{14} = 52 \\ [/tex]

So ;

[tex]x = 52[/tex]

And we're done...

Congruent triangles are similar triangles.

The statement that completes the proof is [tex]\mathbf{\angle ACB \cong ECD}[/tex]

From the complete question (see attachment), we have the following highlights

[tex]\mathbf{AC\cong CE}[/tex].[tex]\mathbf{BC\cong CD}[/tex]

The angle at point C of both triangles are congruent

i.e. [tex]\mathbf{\angle ACB \cong ECD}[/tex]

This means that the missing statement of the proof is that the angles at C of both triangles are congruent.

Hence, the statement that completes the proof is [tex]\mathbf{\angle ACB \cong ECD}[/tex]

Need help urgently with this geometry question

Answers

Answer: Choice B) x = 52

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

Explanation:

The angles (2x+24) and x are same side interior angles. Same side interior angles are supplementary when we have parallel lines.

(2x+24) + (x) = 180

2x+24+x = 180

3x+24 = 180

3x = 180-24

3x = 156

x = 156/3

x = 52

Answer:

72/b = h

Step-by-step explanation:

plug in known values

A = 1/2 (bh)

36 = 1/2 (bh)

goal is to isolate the variable h (height)

multiply both sides by 2 to cancel out 1/2

36 × 2 = 1/2 × 2 (bh)

72 = bh

divide both sides by b (base)

72/b = bh ÷ b

72/b = h

i dont see the value for base given so this would be the final answer as far as i know

What is product of 5.2 · 10^6 and 1.4 · 10^3

Answers

Answer:

7280000000 or 7.28^9 (in scientific notation)

Step-by-step explanation:

this question is asking you to transfer numbers out of scientific notation and multiply them. 10^6 is 1 followed by 6 zeros (good trick to remember) or 1000000. when you multiply anything by a power of 10 you just add that many zeroes to it or move the decimal point one point to the left for every zero. so in this example it is 5.2 times 1000000 which is 5200000. we do the same for the other one and we get 1400. When we multiply these two values we get 7280000000 or 7.28^9
