Answer:

The answer would be 3 times square root of 2 divided by 2. If you use the formula and work backwards, by plugging in each one of these and solving for 90 degrees, you would see that none of them work except this one.

Answer:

x = 3√2 / 2

Step-by-step explanation:

45 45 90 right triangle

Ratio of leg : hypo = x : x√2

Given hypo = 3 so leg = 3√2 / 2

Double check:

leg = 3√2 / 2

hypo = leg √2

= 3√2 / 2 * (√2)

= 3 * 2 / 2

= 3

PLEASE ANSWER THIS AND SHOW WORK. FIND THE SURFACE AREA FOR THE FIGURE BELOW

Varvara68 [4.7K]

Answer:

Total surface area of the given figure is 246.75 square mile.

Step-by-step explanation:

Surface Area of the given figure = Lateral surface area + Area of the base

Lateral surface area of the figure = Sum of the areas of 5 triangular surfaces

= $5(\frac{1}{2} )(\text{Base})(\text{Slant height})$

= $\frac{5}{2}(7)(9.3)$

= 162.75 mi²

Surface area of the pentagonal base = 84 mi²

Total surface area of the figure = 162.75 + 84

= 246.75 mi²

Therefore, total surface area of the given figure is 246.75 square mile.
