Answer:

135°

Step-by-step explanation:

we are given that the bottom leftmost angle is 50, so its opposite angle is 50 since opposite angles are always congruent.

the angle opposite 100 degrees is 100, the last angle in the left triangle is 30 since 180 - 100 - 50 = 30. (all angles in a triangle equal 180)

the angle to the right of the 70 is 80, since a line is a flat angle = 180 and

180-30-70 = 80

the angle opposite 55 is 55

the question mark would be 55+80=135, since the outside angle of a triangle is equivalent to the sum of the farthest 2 inside angles.

Joe measured the diameter of a tennis ball correct to the nearest millimetre. The upper bound of his measurement was 6.75 centim
Mandarinka [93]

The lower bound of the measurement is 65.5 millimetres.

A centimetre equals 10 millimetres, a measure is expressed by the <em>measured</em> magnitude plus uncertainty, the latter one represents the grade of precision of the measure instrument. That is to say:

y = x + \epsilon (1)

Where:

  • x - Measured magnitude, in millimeters.
  • y - Possible magnitude, in millimeters.
  • \epsilon - Uncertainty, in millimeters.

If we know that y = 67.5\,mm and \epsilon = 1\,mm, then the lower bound of the measurement is:

y = 67.5\,mm - 2\cdot (1\,mm)

y = 65.5\,mm

The lower bound of the measurement is 65.5 millimeters.

Pls help I’m so confused
solniwko [45]

Answer:

Yes

Step-by-step explanation:

First, look for the hypotenuse (diagonal) of the base of the box. We have the two legs: 13 inches and 35 inches.

Set up an equation using the Pythagorean theorem:

13^2+35^2=C^2

Solve for C:

169 + 1225 = C^2

1394 = C^2

C ≈ 37.34

Now that we have the diagonal of the base, we know can move on to find the value of the interior diagonal. We have two legs: 13 inches and 37.34 inches.

Again, set up an equation using the Pythagorean theorem, and solve for the new C:

13^2+37.34^2=C^2

1563.2756 = C^2

C = 39.54

The interior diagonal of the box is approximately 39.54 inches long, which is longer than Kylie's baton, which is 38 inches long. So, she can fit the baton in the box.

Have a nice day! :)
