Find the value of x
1 answer:
Answer:
x = 62 degrees
Step-by-step explanation:
Since this is a right angle, we can use trig functions
cos theta = adjacent/ hypotenuse
cos x = 3.7/7.9
Taking the inverse cos of each side
cos ^ -1 ( cos x) = cos ^-1 (3.7/7.9)
x =62.07246803
To the nearest degree
x = 62 degrees

Answer:
1.
cos ∅=b/h=24/25
:.b=24
h=25
by using Pythagoras law
h²=p²+b²
25²=p²+24²
p²=25²-24²
p=√7²=7
now
sin ∅=P/h=7/25
tan∅=p/b=7/24
2.cos ∅ is your answer
sec∅-sin∅tan∅
1/cos∅-sin²/cos∅
(1-sin²∅)/cos∅
cos²∅/cos∅
cos∅
3.
tan²∅-sec²x
sin²∅/cos²∅-¹/cos²∅
(sin²∅-1)/cos²∅
