The given triangle is a right triangle.
The tangent of an angle of right triangle is obtained by dividing the opposite side of the angle with the adjacent side of the angle.
The opposite side of angle R is 5 cm and the adjacent side of angle R is 12 cm.
tan R = 5 / 12 = 0.4167
R = arctan (0.4167) = 22.6 degrees.
Answer: the answer is B. 90√2
Step-by-step explanation:
It is a 45 45 90 triangle and the hypotenuse is always the smaller side (x) root 2
Or x√2
The answer is b I think hope this helps
Answer:
10
Step-by-step explanation:
it is Pythagoras theorem
6*6=36
8*8=64
64+36=100
square root of 100 is 10
Answer:
x = 9√3
y = 18
Step-by-step explanation:
Using SOH CAH TOA
sin (thita) = Opp/hyp
sin 30 = 9/y
y = 9/sin 30
y = 9/0.5
y = 9×2
y = 18
Cos (theta) = Adj/hyp
cos 30 = x/18
x = 18×cos30
x = 18 × √3/2
x = 9√3
