Answer:
148cm^2
Step-by-step explanation:
The formula for surface area of a rectangular prism is 2(hl)+2(hw)+2(wl).
we just plug in the values.
2(6 x 5) + 2(6 x 4) + 2(4 x 5)
= 2(30) + 2(24) + 2(20) then simplify
= 60 + 48 + 40
= 148
So since you haven't given us the actaul equation Im gonna guess that x equals to -7, and lets just say the x equals to uhhhhhh, i dont know how about 42? That sound about right? What im trying to say is next time can you please give out the equation? If you respond I could probably help you next time.
These 2 angles are supplementary so we have
x+ 88 + x + 108 = 180
2x + 196 = 180
2c = -16
x = -8
the 2 angles are -8+88 and -8+108
that is 80 and 100.
All the triangles are similar, so you know the long side is twice the length of the short side.
x = 2·16 = 32
From the Pythagorean theorem,
z = √(8² + 16²) = √320 = 8√5
Then
y = 2z = 16√5
The appropriate choice is the 2nd choice,
x = 32, y = 16√5, z = 8√5
Answer:
Step-by-step explanation:
The 3 angles must add up to 180. So
6x + 4x + 2x = 180
12x = 180
x = 15
Plug this into all the angles and you have your answers
