Answer:
20 +4√2
Step-by-step explanation:
Find the total area the regular pyramid = A + 1/2ps
A is the Base area
p is the perimeter of the base
s is slant height
A = 1/2 * 4 * 4
A = 16/2
A = 8
p = 4 + 4 + (√4^2+4^2)
p = 8 + √32
p = 8 + 4√2
s = 4
Substitute
TSA = 8 + 8 + 4√2 + 4
TSA = 20 +4√2
Hence the total surface area is 20 +4√2
3x^2-12x+1=0
Use formula to solve quadratic eqns
Standard form of quadratic eq is ax^2+bx+c
-b(+,-)sqrtb^2-4ac/2a

Answer:
m∠X = 29°
m∠V = 61°
m∠W == 90°⇒given
Step-by-step explanation:
∵ ΔXWV is right angle at W
∴ m∠W = 90°
∴ m∠X + m∠V = 180° - 90° = 90°
∵ m∠X = 2x + 5 and m∠V = 4x +13
∴ 2x + 5 +4x + 13 = 90
∴ 6x + 18 = 90
∴ 6x = 90 - 18 =72
∴ x = 72/6 = 12
∴ m∠X = 2(12) + 5 = 29°
∴ m∠V = 4(12) + 13 = 61°
