Answer:

PEMDAS

Step-by-step explanation:

Parentheses: (14 - 12) = 2

Exponent: $8^{2}$ = 64

Multiplication: 6(2) = 12

Division: None (It's not necessary for you to do but it's for sake of explanation)

Addition: 64 + 12 = 76

Subtraction: None (Again not necessary for you)

Answer is 76

First determine the missing angle for triangle 1 and triangle 2. Then apply the angle-angle criterion to determine if the two tr

barxatty [35]

Answer:

Triangle 1 – ∠1 = 25°, ∠2 = 115° Triangle 2 – ∠1 = 25°, ∠3 = 40°
Triangle 1 – ∠1 = 5°, ∠2 = 15° Triangle 2 – ∠2 = 15°, ∠3 = 160°

Step-by-step explanation:

You can save yourself some trouble if you realize that one of the angles in one pair must match one of the angles in the other pair.

This observation eliminates the first two choices.

Going further, the triangles will be similar if the dissimilar angles together with one of the similar angles totals 180°.

Triangle 1 – ∠1 = 50°, ∠2 = 30°

Triangle 2 – ∠2 = 20°, ∠3 = 100° . . . . . no angles match

Triangle 1 – ∠1 = 60°, ∠2 = 20°

Triangle 2 – ∠1 = 40°, ∠3 = 100° . . . . . no angles match

Triangle 1 – ∠1 = 25°, ∠2 = 115°

Triangle 2 – ∠1 = 25°, ∠3 = 40° . . . . 25° angles match; 25+40+115 = 180

These triangles are similar.

Triangle 1 – ∠1 = 5°, ∠2 = 15°

Triangle 2 – ∠2 = 15°, ∠3 = 160° . . . . 15° angles match; 15+5+160 = 180

These triangles are similar.

The change in the value of an account when given to the nearest dollar?

devlian [24]

What changes may occur if the given dollar will be rounded off to its nearest value.
There will only be 2 chances, the dollar will become smaller or bigger. Why? 
Because in mathematical rules of rounding off numbers:
number below 5 will be round down and 5 and up will be rounded up.
For example:
You have a bill of $6.79 since the number next to the decimal point in the right is 7, it will be rounded up to $7.
But if your bill is $6.25, it will be rounded down to $6.00
