Answer:
Step-by-step explanation:
Each of the four sides of this triangular prism has height 8 m and base 12 m. The area of each face this thus A = (1/2)(base)(height), or
A = (1/2)(12 m)(8 m) = 48 m^2. The total side area is thus 192 m^2.
This is the surface area. If we want to include the base area, that would be another (12 m)^2 , or 144 m^2.
Answer:
x=±sqrt (33)
Step-by-step explanation:
y=(x+2)(x-2)
29=x^2-4. x^2=33, x=±sqrt (33)
Answer:
117 degrees
so a line is 180 degrees so the 63 +x=180
find x
180-63=117
Answer:
10
Step-by-step explanation:
The sum of exterior angles for any polygon is 360.
so first add up all the given exterior angle:
30+35 = 65.
next, find all the exterior angles that you can find:
Exterior angle = 180-interior angle
so:
180-90 = 90
180-135 = 45
180-120 = 60
180-90=90
These are all that we can find.
now add these to 65:
90+45+60+90+65 = 350
To find x, subtract 350 from 360, which is the sum of exterior angles.
360-350 = 10
Hope this helps
Good Luck
