Answer:

440 cm²

Step-by-step explanation:

To find the surface area, you need to find the area of the two bases (triangles) and three rectangles.

Triangles

A = 1/2Bh

A = 1/2 (8)(7)

A = 1/2 (56)

A = 28

Since there are two of them, you would double that, so the total area of two triangles is 56cm²

Rectangles

A = Bh

A = (16)(8)

A = 128

Since the triangle bases are equilateral triangles, the three rectangles are all congruent. All you need to do is triple the area of one rectangle which gives you 384 cm²

Now just add those two together and you get 440cm²

Solve for the unknown in the following diagram. Round the answer to two decimal places.<br>in<br>​
Alexxandr [17]

Answer:

172.27 in

Step-by-step explanation:

Apply the Sine Rule

Sine Rule is given as:

\frac{a}{sin(A)} = \frac{b}{sin(B)} = \frac{c}{sin(C)}

c = x = ?

C = 180 - (52 + 48) = 80° (sum of triangle)

b = 130 in.

B = 48°

Plug in the values

\frac{130}{sin(48)} = \frac{x}{sin(80)}

Multiply both sides by sin(80)

\frac{130*sin(80)}{sin(48)} = x

172.274641 = x

x = 172.27 in. (to 2 decimal places)
