X - 20 = -35

x - 20 (+20) = -35 (+20)

x = -35 + 20

x = -15

hope this helps

I’ll give brainliest

faust18 [17]

Step-by-step explanation:

Let

c = 11.5 cm

a = 8.9 cm

b = ?

Since this is a right triangle, we can use Pythagorean theorem to find the length of side b:

$c^2 = a^2 + b^2$

$\Rightarrow b^2 = c^2 - a^2$

Taking the square root of the equation above, we get

$b = \sqrt{c^2 - a^2} = \sqrt{(11.5\:\text{cm})^2 - (8.9\:\text{cm})^2}$

$\:\:\:\:=7.3\:\text{cm}$

Regina’s work to find the surface area of a square pyramid from its net is shown below.

Y_Kistochka [10]

She put 12.8 in place of 11.9 in the formula of the triangle. Then the correct option is A.

<h3>What is Geometry?</h3>

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

Regina’s work to find the surface area of a square pyramid from its net is shown below.

A square pyramid. The square base has side lengths of 9.4 inches. The triangular sides have a height of 11.9 inches.

Surface area of the pyramid = 4 [one-half (9.4) (12.8)] + 9.4² = 329 square inches

Then the error done by Regina will be

She should have used One-half (9.4) (11.9) to represent the area of a single triangle.

Then the correct option is A.
