Help please ...a square card has an area of 15 in.^2 what is the approximate side length of the card

11111nata11111 [884]

Area = side length²
Because it's a square, all of the side lengths are equal.
15 = s²
s = √(15)
s = √(15) inches

Hope this helps!

I need the answer to the image

Levart [38]

Answer:

∠B = 156°

Step-by-step explanation:

A line intersects two parallel lines this means that their opposite angles are transversals specifically the angles, A and B. And transversal angles are congruent so I can make this claim below:

$∠A = ∠B \\ 8x +78 = 2x +144$

Solving for x:

$8x +78 = 2x +144 \\ 8x -2x +78 = 2x -2x +144 \\ 6x +78 -78 = 144 -78 \\ 6x = 66 \\ \frac{6x}{6} = \frac{66}{6} \\ x = 11$

Solving Angle B if x = 11.

$∠B = 2x +144 \\ ∠B = 2(11) +144 \\ ∠B = 22 +144 \\ ∠B = 166$
