since it is a quadrilateral, all the sides will add to 360. If two angles are 90, and one is 99, add them and subtract from 360. The last angle should be 81 degrees.

Answer:

A 6 cm²

Step-by-step explanation:

The formula for the Surface Area of a Rectangle Prism and Square Prism [Cube] is below:

S.A = 2hw + 2bw + 2hb

Since 1 is the length of all edges, and also because all edges are congruent on a cube, you plug in 1 for the <em>height</em>, <em>width</em><em>,</em><em> </em>and<em> </em><em>base</em>:

6 = 2[1][1] + 2[1][1] + 2[1][1]

2 2 2

Or, you can just simply plug in 1 into the formula the exercise gave you and be done with it.

I am joyous to assist you anytime.

4) -0.3 = -1/3 < -1/7 since the bigger a negative number is the less positive it is. 1/8 is positive so it is clear that it should be placed last. & thus do all options this way.

5) B

Area of a triangle = ½ bh.

where b = base &

h = height.

Area of outer shape = (½ x 16 x 12) in^2.

= 96 in^2.

Area of unshaded inner shape = (½ x 3 x 4) in^2.

= 6 in^2.

Area of shaded region = (96 – 6) in^2.

= 90 in^2.
