Consider the following statement: The sum of two numbers is always greater than the larger number. Which of the following is tru

e?
A The statement is true because adding is always the act of increasing the size of a quantity; therefore, the new size is always bigger.

B The statement is true because the product of two numbers is always greater than the larger number, and multiplication is just repeated addition.

C The statement is false because any number times zero is zero, with is not larger than the number.

D The statement is false because of the counterexample:

Answer:

C because you are multiplying. Since you can do zero multiplied zero to get zero, therefore, zero has not changed as the bigger number.

The answer is D because when you are adding a negative number the sum will be less the the largest number even though when adding a positive number the sum could end up being larger

What is the value of x?<br><br> x = 45°<br> x = 65°<br> x = 70°<br> x = 115°
dem82 [27]

The three inside angles of a triangle need to equal 180 degrees.

To find X subtract the two known angles from 180.

X = 180 - 45 - 70

X = 65 degrees.

Find m∠STU and m∠TUA
PIT_PIT [208]

Answers:

  • angle STU = 65 degrees
  • angle TUA = 123 degrees

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

Explanation:

Let's find the expression for angle TUS in terms of x

Angle TUA has the expression 11x+2. It will add to angle TUS to get 180 degrees

(angle TUS) + (angle TUA) = 180

angle TUS = 180 - (angle TUA)

angle TUS = 180 - (11x + 2)

angle TUS = 180 - 11x - 2

angle TUS = -11x + 178

Now focus on the interior angles of triangle TUS. We have these three angles

  • T = 5x+10
  • U = -11x+178
  • S = 58

For any triangle, the interior angles always add to 180, so,

T+U+S = 180

(5x+10) + (-11x+178) + (58) = 180

(5x-11x) + (10+178+58) = 180

-6x + 246 = 180

-6x = 180-246

-6x = -66

x = -66/(-6)

x = 11

Use this x value to find the angle measures we're after:

  • angle STU = 5x+10 = 5*11+10 = 55+10 = 65 degrees
  • angle TUA = 11x+2 = 11*11+2 = 121+2 = 123 degrees

--------------------------

As an alternative route, you can apply the remote interior angle theorem. This says that adding two interior angles leads to the exterior angle that isn't adjacent to either one.

In this case, we would say

(angle STU) + (angle TSU) = angle TUA

that leads to the equation

(5x+10) + (58) = 11x+2

Solving this should lead to x = 11 to generate the angles mentioned earlier.
