Answer:

x=4, y=61

Step-by-step explanation:

Since the triangles are congruent, we already know that they have the same angles and sides.

We can solve for the missing side with this equation:

51=12x+3

<em>subtract</em> 3 from both sides

48=12x

<em>divide </em>both sides by 12

x = 4

Due to the Angle Theorems we already know 2 of the angles on the triangle:

63 and 56

We can solve for the missing angle with this equation:

A+B+C=180

63+56+y=180

119+y=180

<em>subtract </em>119 from both sides

y=61

<em>plz mark me brainliest.</em> :)

** Which of the following is parallel to the line 2x + 4y = 16 (A) y = 2x + 5 (B) y = -x + 4 (C) y = -x + 8 (D) y = 2x + 5 =-​
andreev551 [17]

Answer:

None of them.

Step-by-step explanation:

Each and every straight line is of one kind in terms of its pattern: it can be presented in the view of y = kx + b: k is the slope or gradient of the line, b is the y-intercept of the line. I will not let the cat out of the bag if I say that any parallel lines do not intersect one another, hence they should have the same value of coefficient k.

2x + 4y = 16 \Leftrightarrow x + 2y = 8 \Leftrightarrow 2y = -x + 8 \Leftrightarrow y = - \frac{1}{2}x + 4

Therefore, our line has k = - \frac{1}{2} and b = 4 coefficients.

(A) k = 2, b = 5;

(B) k = -1, b = 4;

(С) k = -1, b = 8;

(D) k = 2, b = 5;

Recapitulating this: none of them have the same coefficient k, thus none of them suit us.
