Pythagorean theorem:

a^2 + b^2 = c^2

12^2 + b^2 = 24^2

144 + b^2 = 576

b^2 = 432

b=20.8

Find lateral surface area in square units, of the following 3-

Sedaia [141]

Answer:

Lateral surface area of cuboid = 448 ft²

Step-by-step explanation:

Given:

Height of cuboid(h) = 14 ft

Length of cuboid(l) = 9 ft

width of cuboid(b) = 7 ft

Find:

Lateral surface area of cuboid

Computation:

Lateral surface area of cuboid = 2 h(l + b)

Lateral surface area of cuboid = 2(14)(9 + 7)

Lateral surface area of cuboid = 28(16)

Lateral surface area of cuboid = 448 ft²

Can someone help me please?

vlabodo [156]

Step-by-step explanation:

ZX is the diameter of the circle with center A.

$\therefore m\angle YAZ + m\angle XAY = 180°\\\therefore (5w+4)°+(11w)°= 180°\\\therefore (16w+4)° = 180°\\\therefore 16w+4 = 180\\\therefore 16w = 180 - 4\\\therefore 16w = 176\\\therefore w = \frac{176}{16}\\\therefore w =11\\ \therefore m\angle YAZ = (5w+4)°\\\therefore m\angle YAZ = (5\times 11+4)°\\\therefore m\angle YAZ = (55+4)°\\\therefore m\angle YAZ = 59°\\\because \overset{\frown}{YZ) = m\angle YAZ\\\therefore \overset{\frown}{YZ) = 59°\\$
