Answer:

  • B. 80°

Step-by-step explanation:

<u>The triangle in the middle has angles that:</u>

  • Supplementary with 110°
  • Supplementary with 150°
  • Same with x, as alternate exterior angles are congruent

Interior angles of a triangle sum to 180°

<u>Find x:</u>

  • x + (180° - 110°) + (180° - 150°) = 180°
  • x + 70° + 30° = 180°
  • x + 100° = 180°
  • x = 80°

Correct choice is B

A rectangular prism with dimensions 5 inches by 13 inches by 10 inches was cut to leave a piece as shown in the image. What is t
vesna_86 [32]

Answer:

Volume of the piece in the picture = 350 cubic inches

Volume of the remaining piece = 300 cubic inches

Step-by-step explanation:

Given question is incomplete without the picture; here is the picture as an attachment.

Volume of the rectangular prism = Length × width × height

V = 5 × 13 × 10

  = 650 cubic inches

Now volume of the piece given in the picture = Volume of prism at the base + Volume of the prism with triangular base

= 10×5×1 + (\text{Area of the triangular base})\times (\text{Height})

= 50 + \frac{1}{2}\times (12\times 5)\times 10

= 50 + 300

= 350 cubic inches

Volume of the other piece = 650 - 350

                                            = 300 cubic inches
