Question

PLEASE HELP! math is stressing me

Answer 1

Sin theta= a/c

= 5/7.8

= 0.64

= 1

Explanation:

Lets find the hypotenuse first by applying Pythagorean theorem.

a^2+b^2=c^2

(6)^2+(5)^2=c^2

36+25=c^2

61=c^2 (FIND SQUARE ROOT)

7.8=c

Sin theta= a/c

= 5/7.8

= 0.64

= 1

Cos theta= b/c

= 6/7.8

Tan theta= a/b

= 5/6
