In triangle ABC, the size of angle B is 4 times the size of angle A, and the size of angle C is 6°

amid [387]

Answer:

<A = 18.6 Degree

<B =74.4 Degree

<C = 87 Degree

Step-by-step explanation:

Sum of all the angles of triangle is 180

as given ,

<A = ?

<B = 4<A

<C = 5 <A - 6

As per rule ,

<A + <B +<C = 180

<A + 4 <A + 5<A - 6 = 180

10 <A - 6 = 180

10 <A = 180 + 6

<A = 186 / 10

<A = 18.6 Degree

Hence ,

< B = 4 X (18.6)

< B = 74.4 Degree

and

<C = 5 (18.6) - 6

<C = 87 Degree

PROOF

<A + <B + <C = 180

18.6 + 74.4 + 87 = 180

180 = 180

The consumption of a vegetable has decreased. The consumption per capita in 2000 was 22.8 pounds, and in 2010, the consumption

Varvara68 [4.7K]

So... if we take 22.8 to be the 100%, then it dropped to 12.1,
the difference in between being 22.8 - 12.1 or 10.7 decrease

so... what is 10.7 in percentage, of 22.8?
well
$\bf \begin{array}{ccllll}
amount&\%\\
\textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\
22.8&100\\
10.7&x
\end{array}\implies \cfrac{22.8}{10.7}=\cfrac{100}{x}$

solve for "x"
