Question

solve qno no 66 as soon as possible​

Answer 1

Answer:

SinΦ= 3/5 = P/H

then base= B = √(H^2-P^2)=√16 =4

then...

CosΦ= B/H = 4/5 Answrr

hope it helps

Answer 2

Answer:

OPTION (A) IS CORRECT THAT IS 4/5

Step-by-step explanation:

WE HAVE TWO SIDES OF A RIGHT ANGLED TRIANGLE

$\sin(Ѳ) = \frac{p}{h} = \frac{3}{5}$

□h=5

□p=3

□b=?

${h}^{2} = {p}^{2} + {b}^{2} \\ {5}^{2} = {3}^{2} + {b}^{2} \\ 25 - 9 = {b}^{2} \\ b = \sqrt{16} \\ b = 4 \\ \cos(Ѳ) = \frac{b}{h} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{4}{5}$
