Answer:
(a) 3x+28+5x+52+2x-10=180 (∠ sum of Δ)
10x+70=180
10x=110
x=11
(b) ∠C = 2x-10
= 2(11)-10
= 12°
The volume of the rectangular pyramid with the given dimensions is: 1,890 cubic millimeters.
<h3>What is the Volume of a Rectangular Pyramid?</h3>
Volume of rectangular pyramid = 1/3(length × width × height)
Given the following:
- Length = 21 mm
- Width = 18 mm
- Height = 15 mm
Volume of the rectangular pyramid = 1/3(21 × 18 × 15)
Volume of rectangular pyramid = 1,890 cubic millimeters.

The probability that more than 5 students will pass their exam is 0.0188416.
<h3>How to find the probability?</h3>
The probability that a student passes their examination = 40% = 0.4
The probability that more than 5 students pass their statistics exam = Probability that 6 students pass their exam + Probability that 7 students pass their exam
The probability that 6 students pass their exam =

The probability that 7 students pass their exam =

The probability that more than 5 students pass their statistics exam = 0.0172032 + 0.0016384
= 0.0188416
Therefore, we have found the probability that more than 5 students will pass their exam to be 0.0188416.
