The coordinates of triangle DEF are D(4,2), E(7,2), and F(6,8). If you translate triangle DEF 4 units right and 3 units down,

rosijanka [135]

Answer:

E’ is (11,-1)

Step-by-step explanation:

Here, we want to get the new coordinates of E

The translation is 4 units right ( add 4 to x-value) and 3 units down ( subtract 3 from y-value)

So for E, we have

(7 + 4, 2-3)

= (11, -1)

Using the sine rule, calculate the length y. Give your answer to 2 s.f.

Tpy6a [65]

Answer:

y = 9.84 mm

Step-by-step explanation:

Law of sine:

$\sf \boxed{\bf \dfrac{a}{Sin \ A}=\dfrac{b}{Sin \ B}= \dfrac{c}{Sin \ C}}$

a = y

A = 31°

b = 17 mm

B = 117°

$\sf \dfrac{y}{Sin \ 31^\circ}=\dfrac{17}{Sin \ 117^\circ}\\\\$

$\sf y = \dfrac{17}{Sin \ 117^\circ}*Sin \ 31^\circ\\\\ y = \dfrac{17}{0.89}*0.515\\\\y = 9.84 \ mm$
