In triangle ABC, the measure of ∠B is 90°, BC=16, and AC=20. Triangle DEF is similar to triangle ABC, where vertices D, E, and F
Andreas93 [3]
  • AC=Hypotenuse=20
  • BC=Base=16

AB:-

Apply Pythagorean theorem

\\ \rm\rightarrowtail P^2=H^2-B^2

\\ \rm\rightarrowtail P^2=20^2-16^2

\\ \rm\rightarrowtail P^2=400-256

\\ \rm\rightarrowtail P^2=144

\\ \rm\rightarrowtail AB=12

Now

  • DE=AB/3=12/3=4
  • EF=BC/3=16/3=5.3
  • DF=AC/3=20/3=6.6

Now

\\ \rm\rightarrowtail sinF=\dfrac{DE}{DF}

\\ \rm\rightarrowtail sinF=\dfrac{4}{6.6}

\\ \rm\rightarrowtail sinF=0.61

In the xy-plane, the point (p, r) lies on the line with equation y = x + b, where b is a constant. the point with coordinates (2
erastovalidia [21]
Each point should satisfy the equation of the line it belongs to.
This means that:
for the equation of the first line (y=x+b), the point (p,r) satisfies this equation, thus: r = p + b ....................> equation I
for the equation of the second line (y=2x+b), the point (2p,5r) satisfies this equation, thus: 5r = 4p + b ...................> equation II
Subtract equation I from equation II to eliminate the constant b:
5r-r = 4p+b-p-b
4r = 3p
Thus, r/p = 3/4
