A triangle cannot have two right angles because the sum of all three angles of a triangle is 180. If there were two right angles in a triangle, then the two angles themselves would equal to 180 degrees, without adding the third angles. Since the degrees added up would have to equal 180 and with two right angles it would be more than 180, there cannot be two right angles in a triangle.
The statement that is not true about the given trigonometric graph is; Option A: The vertical phase shift of y = 3 sin(-5x - π/2) - 6 is; π/5
<h3>How to Interpret Trigonometric Graphs?</h3>
Let us analyze the options;
A) For the give equation;
y = 3 sin(-5x - π/2) - 6
From the general equation given we can say that;
A = 3
B = 5
C = -π/2
D = -6
Thus, phase shift = C/B = -(π/2)/5
Phase Shift = -π/10.
Thus, option A is not correct.
B) Period = 2π/B
Thus; Period = 2π/5
Formula for frequency from period is;
Frequency = 1/period
Thus, it is correct that Period and frequency vary indirectly
C) As B gets bigger, the period gets smaller and the frequency gets greater. Thus, this option is correct
D) This statement is correct.
