In triangle ABC and PQR,

  • Angle A = Angle P

( they are equal, measures 60° each )

  • Angle B = Angle Q

( they are equal, measures 43° each )

so, the given triangles are Similar by

=》AA Similarity criterion

now, since the triangles are similar

the corresponding sides will be proportional,

=》

\frac{AC }{PR}  =  \frac{BC }{QR}

=》

\frac{6}{15}  =  \frac{9}{y}

=》

\frac{2}{5}  =  \frac{9}{y}

=》

2y = 45

(by cross multiplication)

=》

y = 22.5

value of y = 22.5 cm

FUNCTIONS QUESTION-----IF YOU ARE A GOOD PERSON PLZ SOLVE THIS FOR ME PLZ I WILL FOREVER BE GRATEFUL♥' GRAPH INCLUDED
stira [4]

Answer:

(a) Domain: x > 4

(b) Range: y < -2

Step-by-step explanation:

Domain is the set of x-values that can be inputted into function f(x).

Range is the set of y-values that can be outputted by function f(x).

We see that our x-values span from 4 to infinity. Since it is an open dot, we cannot include it in our domain:

(-4, ∞)

We also see that our y-values span from -2 to negative infinity. Since it is an open dot, we cannot include it in our range:

(-∞, -2)
