Question

Hello I need help with question 6! I will give you a great rating! Please help, I’m not sure how to do this. Also this is not a quiz this is practice

Answer 1

6.

cos a = adjacent side / hypotenuse

Replacing with the values given:

Cos 45 = 13 / y

y= 13/cos45

y= 13/ (1 /√2 )

Y= 13√2

For x apply the Pythagorean theorem

c^2 = a^2 + b^2

Where:

c= hypotenuse

a & b = the other 2 legs

(13 √2 )^2 = x^2 + 13^2

338 = x^2 + 169

338 - 169 = x^2

169 =x^2

√169 = x

x = 13
