Answer:

x  = ±5

Step-by-step explanation:

4x^2 = 100​

Divide each side by 4

4/4x^2 = 100/4

x^2 = 25

Take the square root of each side

​sqrt(x^2) = ±sqrt(25)

x  = ±5

Use a graphic organizer to compare and contrast similar and congruent figures
Anika [276]
Similar figures are figures of the same shape but different (or same) size.
Thus, they look the same, but one is bigger than the other by a scale factor.

Congruent figures are figures of the same shape AND same size.
They can be mapped onto each other using any type of transformation (besides dilations).

Similar figures can be dilated.

Answer:

A. 51°

Step-by-step explanation:

By the theorem of intersecting secants.

m\angle B=\frac{1}{2} (m\widehat{LW} - m\widehat{MU})

44.5\degree =\frac{1}{2} (140\degree - m\widehat{MU})

2\times 44.5\degree = 140\degree - m\widehat{MU}

89\degree = 140\degree - m\widehat{MU}

m\widehat{MU} = 140\degree -89\degree

m\widehat{MU} = 51\degree
