Answer:

Step-by-step explanation:

Volume = (1/3)*B * h

B = 1/2 * a * b

a = 3

b = 4

B = 1/2 * 3 * 4 This only works because the base is a right triangle.

B = 6

Volume = 1/3 * 6 * 6

Volume = 1/3 * 36

Volume = 12

Answer:

$\boxed{\sf \huge \boxed{ \sf ?} = 6}$

Step-by-step explanation:

$\sf Solve \: for \: \boxed{ \sf ?} : \\ \sf \implies \frac{\boxed{ \sf ?}}{5} \times \frac{10}{8} = 1.5 \\ \\ \sf \implies \frac{\boxed{ \sf ?} \times 10}{5 \times 8} = 1.5 \\ \\ \sf \frac{10}{5} = \frac{ \cancel{5} \times 2}{ \cancel{5}} = 2 : \\ \sf \implies \frac{ \boxed{ \sf 2} \times \boxed{ \sf ?} }{8} = 1.5 \\ \\ \sf \frac{2}{8} = \frac{ \cancel{2}}{ \cancel{2} \times 4} = \frac{1}{4} : \\ \sf \implies \frac{\boxed{ \sf ?}}{ \boxed{ \sf 4}} = 1.5 \\ \\ \sf Multiply \: both \: sides \: of \: \frac{\boxed{ \sf ?}}{4} = 1.5 \: by \: 4 : \\ \sf \implies \frac{4 \times \boxed{ \sf ?}}{4} = 4 \times 1.5 \\ \\ \sf \frac{4 \times \boxed{ \sf ?}}{4} = \frac{ \cancel{4}}{ \cancel{4}} \times \boxed{ \sf ?} = \boxed{ \sf ?} : \\ \sf \implies \boxed{\boxed{ \sf ?}} = 4 \times 1.5 \\ \\ \sf 4 \times 1.5 = 6 : \\ \sf \implies \boxed{ \sf ?} = 6$

the sum of all but one interior angle of a heptagon is 776°. what is the measure of the final interior angle?

soldi70 [24.7K]

Answer:

The final interior angle = 124°

Step-by-step explanation:

A heptagon has 7 sides. The sum of the interior angles formula:

The sum of the interior angles = (n - 2)180 where n = number of sides.

The sum of the interior angles= (7 - 2)180° = 900°

Six interior angles = 776°.

The final interior angle + six interior angle = 900°

The final interior angle + 776° = 900°

The final interior angle = 900° - 776°

The final interior angle = 124°
