If the dimensions are multiplied by 1/4, we have that the surface area will by multiplied by (1/4)^2, as the dimensions are in inches and the surface area is in inches squared.

So, If the original surface area is 1936 inches squared, the new surface area will be:

New surface area = 1936 * (1/4)^2 = 1936 / 16 = 121 inches squared.

PLS HELPPPPPP!!!!!!!!!!

Answer:

x = 30

ABC = 90

ACB = 30

Step-by-step explanation:

We know that if we add the 3 angles of a triangle together, it will come out to be 180 degrees, so..

60 + x + 3x = 180 subtract 60 from both sides and simplify

4x = 120 divide both sides by 4

x = 30

ABC = 3x

ABC = 3(30)

ABC = 90

Can someone show the work on this problem

Masja [62]

Answer:

4.69 in

Step-by-step explanation:

By sine rule:

$\frac{ \sin \: 23 \degree}{a} = \frac{ \sin \: 90 \degree}{12} \\ \\ \frac{ \sin \: 23 \degree}{a} = \frac{1}{12} \\ \\ a = 12 \: \sin 23 \degree \\ \\ a = 12 \times 0.3907311285 \\ \\ a = 4.68877354 \\ \\ a \approx 4.69\: in$
