Answer:

B. BC ≅ CE is correct.

Step-by-step explanation:

We are given that, ΔABC ≅ ΔEDC.

As, we know, when two triangles are congruent, their corresponding sides and corresponding angles are congruent.

So, we get from ΔABC ≅ ΔEDC,

AB ≅ ED, BC ≅ DC and AC ≅ EC

∠A ≅ ∠E, ∠B ≅ ∠D and ∠C ≅ ∠C.

Thus, we have,

Options A, C and D, being true are not correct.

But, option B i.e. BC and CE may not necessarily be congruent.

Hence, option B is correct.

It would be B, because BC does not necessarily have to be equal to CE, as they are not congruent

What is the value of x?
Ratling [72]

Answer:

4x+7 = 5x-20                  

(reason: vertical angles are congruent; property used: distributive)

7 = 1x-20

1x = 7+20

1x = 27

x = 27

Vector V is in standard position and makes an angle of 50° with the positive x-axis. Its magnitude is 18. Write V in component f
Umnica [9.8K]

Answer:

11.57 units east, 13.79 units upwards

11.57i + 13.79j

Step-by-step explanation:

V = 18 units at an angle of 50° to the positive x-axis

In component Form, this is how each component is calculated

a = 18cos50° = 11.57 units east

b = 18sin50° = 13.79 units upwards

check if your answer is correct

\sqrt{11.57^{2} +13.79^{2} } = 18.0

In vector component form ai + bj = 11.57i + 13.79j

What is the y intercept of 2y - 2x = 8
Firdavs [7]

Answer:

Step-by-step explanation:

Write in y = mx + b form

here, b ----> y intercept

2y - 2x = 8

     2y = 2x + 8         {Divide the equation by 2}

       \frac{2y}{2}=\frac{2x}{2}+\frac{8}{2}\\

        y = x + 4

y-intercept = 4
