Answer:
236.3 feet squared.
Step-by-step explanation:
Base Surface Area = 8 squared
= 64 feet squared
Lateral Surface Area =
2×8× √
( 8 )2 + 102
2
= 172.3 feet sqaured
Total Surface Area = 236.3 feet squared

2, left direction (or negative if that’s an option)
Answer:
The required answer is
Therefore the number in green box should be 7.
Step-by-step explanation:
Given:
AB = 7√2
AD = a , BD = b , DC = c , AC = d
∠B = 45°, ∠C = 30°
To Find:
c = ?
Solution:
In Right Angle Triangle ABD Sine identity we have

Substituting the values we get


Now in Triangle ADC Tangent identity we have

Substituting the values we get

The required answer is
We know that
in the right triangle
sin x=opposite side angle x/hypotenuse
opposite side angle x=66 mm
hypotenuse=79 mm
so
sin x=66/79
x=arc sin (66/79)-------> x=56.66°-------> x=56.7°
the answer is
x=56.7°
