Answer:

($4.30 × 3)(3c) = $19.50

c = $2.20

Step-by-step explanation:

($4.30 × 3)(3c) = $19.50

(12.90)(3c) = 19.50

3c = 6.60

c = 2.20

(u had most of the equation laid out already, u were just missing 3c)

For ΔABC, ∠A = 3x - 8, ∠B = 5x - 6, and ∠C = 4x + 2. If ΔABC undergoes a dilation by a scale factor of 1/2 to create ΔA'B'C' wit

Answer:

D. ∠B = ∠B' = 74° and ∠C = ∠C' = 66°

Step-by-step explanation:

Given,

$\angle A=3x-8\\\angle B=5x-6\\\angle C=4x+2$

We know,sum of all 3 angles of a triangle is $180$ °

Doing so ,

$\angle A+\angle B+\angle C=180\\3x-8+5x-6+4x+2=180$

Simplifying all like terms,

$12x-12=180\\12x-12+12=180+12\\12x=192$

Dividing both side by 12

$x=\frac{192}{12}$

$x=16$

Now we plug this in each angles and find their exact values.

$\angle A=3x-8=(3\times16)-8=48-8=40$ °

$\angle B=5x-6=(5\times16)-6=80-6 =74$ °

$\angle C=4x+2 = (4\times16)+2=64+2=66$ °

Now substituting the $x=16$ in angles of dilated triangle.

$\angle A'=(2\times16)+8=32+8= 40$ °

$\angle B'=90-16=74$ °

$\angle C'=(5\times16)-14=80-14=66$ °

We see that all the corresponding angles are equal and as far as the options are concerned only option (D) matches.
