First of all, just to avoid being snookered by a trick question, we should verify that these are really right triangles:
7² + 24² really is 25² , and 8² + 15² really is 17² , so we're OK there.
In the first one:
sin(one acute angle) = 7/25 = 0.28
the angle = sin⁻¹ (0.28) = 16.26°
the other acute angle = (90° - 16.26°) = 73.74°
In the second one:
sin(one acute angle) = 8/17 = 0.4706...
the angle = sin⁻¹ (0.4706...) = 28.07°
the other acute angle = (90° - 28.07°) = 61.93°
I'm sorry, but just now, I don't know how to do the
third triangle in the question.
Degree of ploynominal is the largest exponent you find, which is here the 4x to the 6th. there are only two terms here.
A right angle is 90 degrees
So you 90/4=22.5
Then 90+22.5=112.5
Hope this helped!

Answer:
A
Step-by-step explanation:
The equation representing a proportional relationship is
y = kx ← k is the constant of proportion
The only equation in this form is
y = 24x ( k = 24 ) → A
