Answer:
Arnez is 4. Andell is 13. Marianne is 7.
Step-by-step explanation:
Let x represent Arnez's age. If we write out an equation, we end up with this:
24 = (9 + x) + (x + 3) + x
24 = 9 + x + x + 3 + x
24 = (x + x + x) + (9 + 3)
24 = 3x + 12
24 - 12 = 3x + 12 - 12
12 / 3 = 3x / 3
4 = x
The measure of angle BC (m ∠BC) is 90°
<h3>Perpendicular lines</h3>
From the question, we are to determine the measure of angle BC
From the given information, we have that
B P ⊥ P C
This means line BP is <u>perpendicular</u> to line PC
The angle between two perpendicular lines is 90°
Hence, the measure of angle BC (m ∠BC) is 90°.

The answer is 12.6
419 is 420 because we are estimating so find 1% of 420 which is 4.2 then multiply 4.2×3 to get 12.6
