Anestetic [448]

Answer:

A triangle is equilateral if all three angles are same. but here two angles are 64° but third angle is 52°. so, Yin is incorrect.

Step-by-step explanation:

x = 19,

Putting value of x to find m∠ABC and m∠ACB

m∠ABC = (4x – 12)°

m∠ABC = (4(19) – 12)°

m∠ABC = (76 – 12)°

m∠ABC = 64°

m∠ACB = (2(19) + 26)°

m∠ACB = (38 + 26)°

m∠ACB = 64°

now we know sum of angles of triangle is 180°. We can find the measure of third angle.

180 = 64+64 +x

x= 180 - 64 - 64

x = 52°

A triangle is equilateral if all three angles are same. but here two angles are 64° but third angle is 52°. so, Yin is incorrect.

Shtirlitz [24]

Answer:

`Part A:

D. 3/4(18 + s) = 31.50

Part B:

$36

Step-by-step explanation:

I think 34 is 3/4, is that right?

here, s is the cost of the skirt

Part A: The answer would be:

3/4(18) + 3/4(s) = 31.5 =

3/4(18 + s) = 31.5

Part B: 3/4(18) + 3/4(s) = 31.5

4.5 + 3/4s = 31.5

Subtract 4.5 from both sides:

3/4s = 27, 27 is the cost of the skirt now, but we need the original price.

multiply both sides by 4/3:

s = 36
