The angles must be acute and all the measured angles must be different.
<h3>What is a triangle?</h3>
This a shape with 3 sides and angke
If in ΔNOP, OP = 7, PN = 13, and NO = 19, then the measure of the angles must be different as well;
Hence the statement that must be true about the angles is that the angles must be acute and all the measured angles must be different. The given triangle must also be a scalene triangle

Convert miles/hour to meters/second:
42mi/hr(0.447) = 18.77m/sec
Answer:
11.176 meters/second
Step-by-step explanation:
1 mile = 1609.34 meters
25 miles = 40233.6 meters
1 hour = 60 minutes
1 minute = 60 seconds
1 hour = 3600 seconds
40233.6 / 3600,
11.176 meters/second
<h3>Part 1</h3>
If we simplify, both Joe and Hope factored the polynomial correctly but Joe didn't complete it fully.
<u>The first binomial can be further factored:</u>
<h3>Part 2</h3>
The quadratic expression needs to have two roots in order to be factored as two binomials.
<u>The discriminant must be positive or zero:</u>
We have a = 3, b = k, c = -8
<u>So we get following inequality:</u>
- k² - 4*3*(-8) ≥ 0
- k² + 96 ≥ 0
<u>Since k² is positive for any value of k, the solution is any value of k:</u>
