Answer:

$58 m^{2}$

Step-by-step explanation:

Seperate it into two pieces;

Piece 1, base of 2, height of 9

Piece 2, base of 8, height of 5.

Area of Piece 1:

A = bh

A = 2 (9) = 18

Area of Piece 2:

A = bh

A = 8 (5) = 40

Add the areas of both pieces:

18 + 40 = 58 m2

Find c. Round to the nearest tenth.

bija089 [108]

Answer:

Step-by-step explanation:

A = 150°

B = 12°

C = 180 - (150 + 12) = 18°

b = 10 cm

Apply the sine rule:

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

Plug in the values

$\frac{10}{sin(12)} = \frac{c}{sin(18)}$

Multiply both sides by sin(18)

$\frac{10}{sin(12)}*sin(18) = \frac{c}{sin(18)}*sin(18)$

$\frac{10*sin(18)}{sin(12)} = c$

c = 14.9 cm (nearest tenth)

7,16,8,27,9 what number continues this pattern

Aloiza [94]

The sequence seems to be that you add 1 and then multiply by 2, and then add 1 and multiply by 3, so I would assume you do 9 + 1 = 10, and then multiply by 4 to get 40 as your next number. I hope this helps!
