Here, sum of all the angles would be equal to 360.
We can see there are two right angles (=90)
So, 90 + 90 + x + 60 = 360
240 + x = 360
x = 360 - 240
x = 120
In short, Your Answer would be 120
Hope this helps!
Answer:
12 feet
Step-by-step explanation:
w = width
w+2 = length
w(w+2) = 8
w² + 2w - 8 = 0
(w+4)(w-2) = 0
w = -4 <em>exclude because a length cannot be negative</em>
w = 2
length = 2+2 or 4
P = 2(2)+2(4)
P = 4+8 or 12
Answer:
408 in²
Step-by-step explanation:
A rectangular prism has 6 rectangular faces.
Opposite faces are congruent
2 faces at (6 × 9) = 2 × 54 = 108 in²
2 faces at (9 × 10) = 2 × 90 = 180 in²
2 faces at (6 × 10) = 2 × 60 = 120 in²
surface area = 108 + 180 + 120 = 408 in²
