Answer:

  • x = 8

Step-by-step explanation:

Let the center be O.

LOH and KOI are congruent as vertical angles.

Angle measure of KOI is the sum of KOJ and JOI.

mKJ = m∠KOI as central angle has same value as intercepted arc.

<u>So we have:</u>

  • m∠LOH = m∠KOI
  • m∠LOH = m∠KOJ + m∠JOI
  • 120 = (7x + 9) + (6x + 7)

<u>Solve for x:</u>

  • 13x + 16 = 120
  • 13x = 104
  • x = 104 / 13
  • x = 8

\huge\mathcal\gray{Answer}

x = 8

\huge\it\blue{explaination}

120°=7x + 9 + 6x + 7

120° = 13x + 16

13x = 120 - 16

13x = 104

x = 8

Work out the volume of this prism.
aniked [119]

Answer:

Volume = 175 cm³

Step-by-step explanation:

We can picture this image as a whole rectangular prism, with a part that has been cut out of it.

Step 1: Volume of original prism

We are going to solve the volume of the original prism, with the dimensions of 9, 7, and 5

  • V = 9 * 7 * 5
  • V = 315

Step 2: Volume of part cut out

We are solving the volume of that part that has been cut out ( missing space)

  • V = 5 * (9-2) * (7-3)
  • V = 5 * 7 * 4
  • V = 140

Step 3: Total Volume

Now we just subtract the cutout part from the original volume

  • 315 - 140
  • V = 175

Volume = 175 cm³

Note, we could have also found the volume by splitting this shape into two prisms with dimensions (9 * 3 * 5) and (4 * 5 * 2). This way would also get us:

  • V = (9 * 3 * 5) + (4 * 5 * 2)
  • V = 135 + 40
  • V = 175
