Question

Pls help me with trig! i would rlly appreciate

Answer 1

`6 √(61) / 61`

is ans

Explanation:

given, a=5 and b=6

as the refrence angle is thit

p=6 and b= 5

`now \: h \: = \sqrt{p {}^(2) + b {}^(2) }`

`= \sqrt{6 { }^(2) + 5 {}^(2) }`

`√(61) =`

therefore h

`= √(61)`

now cos thita =b/h

therefore cos thita=

`6 √(61) / 61`

...is ans..

Answer 2

c≤

Explanation:

hypotenuse=√(a²+b²)=√(5²+6²)=√(25+36)=√61

cosθ=5/√61=5/√61× (√61/√61)=5√61/61
