Answer:
12
Step-by-step explanation:
The diagram shows a right angle, therefore (6x-2) + 20 = 90.
<u>Find x</u>
(6x - 2) + 20 = 90
6x - 2 = 70
6x = 72
x = 12
<u>Confirmation</u>
[6(12) - 2] + 20 = 90
Answer:
A) -68
Step-by-step explanation:
Answer:
0.65 square inch
Step-by-step explanation:
Each triangle has an area given by ...
A = 1/2bh = 1/2·(0.5 in)(0.4 in) = 0.10 in²
The square base has an area given by ...
A = s² = (0.5 in)² = 0.25 in²
The total area is that of the square base and 4 triangles:
S = 0.25 in² + 4×0.10 in² = 0.65 in²
I believe that angle 6 is 108 because I drew to the best of my ability and I see that 3 and 6 are alternate interior angles.
The edge represented by EA is the edge skewed to edge FG. Skew lines are non-intersecting lines in space. These lines are neither parallel nor they form right angles.
