Answer:

1)107

2)43

Step-by-step explanation:

Triangles interior angles add up to 180 degrees. In the first one, the first two angles are 31and 42, and if interior angles add up to 180, the equation should be 31+42+x=180 x=107.

Second one is hardes. A square means a right angle, or 90 degrees. 180-90 is 90. Next, we have the two angles x, and x+4 We know that triangles interior angles add up to 180 degrees, so x+x+4+90=180 2x+94=180 2x=86 x=43

Hope this helps :D Please mark brainliest if correct :D

Part A

  • Converse = "If corresponding angles are equal, then two lines are parallel"
  • Result = True

Explanation:

Refer to the converse of the corresponding angles theorem. The original version is stated as part A, and the converse is marked in bold above.

Conditional statements are of the form "if this, then that". Symbolically we can use the template "If P, then Q". The P and Q are placeholders for logical statements.

The converse of "if P, then Q" is "If Q, then P". We swap the positions of P and Q. Do not negate either piece.

========================================================

Part B

  • Converse = "If angle C is 70 degrees, then the sum of angles A and B is 110 degrees"
  • Result = True

Explanation:

Recall that for any triangle, the three interior or inside angles always add to 180 degrees. In short: A+B+C = 180. If C = 70, then A+B = 180-C leads to A+B = 180-70 and A+B = 110. This process can be reversed.

========================================================

Part C

  • Converse = "If two lines are not parallel, then alternate interior angles k and s are not equal"
  • Result = True

Explanation:

For more information, check out the converse of the alternate interior angles theorem. The regular version of the theorem is "If two lines are parallel, then the alternate interior angles are congruent".

The converse of this theorem flips things to say: "If alternate interior angles are congruent, then the lines are parallel".

========================================================

Part D

  • Converse = "If John loses his money, then he throws coins in the fountain"
  • Result = False

Explanation:

Throwing coins in a fountain is one way to lose money, but there are other ways. He could drop a coin somewhere, or leave the coin somewhere he forgot.

In other words, just because he lost his money does not mean he threw a coin in the fountain.

What is 56.398 rounded to the nearest tenth
Ratling [72]

The decimal place to the right of the tenths place is the hundredths place. The digit in that place is 9.

When the digit to the right of the place you're rounding to is more than 4, you increase the digit in the rounding place by 1.

Here, we have the hundredths digit is 9, which is more than 4, so we increase the tenths digit by 1. The rounded number is

... 56.4

_____

Another way to get there is to add 5 in the hundredths place (the place to the right of the one you're rounding to). When you do that, you get 56.448. Now, throw away all the digits to the right of the one you're rounding to. This leaves

... 56.4

_ _ _ _ _ _ _

The reason I show this last method is to deal with cases like rounding 56.978. By the first rule, you're increasing the digit 9 by 1, which might be confusing. (it requires a carry into the next digit, making 57.0.) If you add .05 to this number, you get 56.978 +.05 = 57.028. Now when you throw away the digits to the right of the tenths digit, you have 57.0.
