Answer:

See below

Step-by-step explanation:

Statement | Reason

1. m∠A + m∠B + m∠C = 180° | 1. Angles in a triangle sum to 180°

2. 28° + x - 4° + 2x = 180° | 2. Substitution

3. x=(180° - 24°)/3= 156°/3°= 52° | 3. Algebra

Clockwise from the obtuse angle, the side ratios are ...

Fig I : Fig II

4.2 : 3.15

y : 6

7 : 5.25

6 : x

4 : 3

A true proportion will have corresponding parts of these ratios in corresponding places. The only true proportion listed is ...

$\dfrac{y}{6}=\dfrac{7}{5.25}$

What is the value of this expression when a = 4, b = -5, and c = -7?

Ganezh [65]

Answer:

The value of the given expression is -878.08.

Step-by-step explanation:

Here, the given question is INCOMPLETE.

The complete question is:

Evaluate the expression for a = 4, b = -5, and c = -7. $4a^2b^{-2}c^3$

Here, substitute the vale of a = 4, b = -5 and c = -7, we get:

$4a^2b^{-2}c^3 = (\frac{4a^2c^3}{b^2}) = (\frac{4(4)^2(-7)^3}{(-5)^2})\\= (\frac{64 \times 343}{25}) =\frac{21,952}{25} = 878.08\\\implies 4a^2b^{-2}c^3 = 878.08 ( a = 4, b = -5 ,c = -7)$

Hence, the value of the given expression is -878.08.
