A right triangle has one angle that measure 23. The adjacent leg measures 27.6 cm and the hypotenuse measure 30 cm. What is the
approximate area of the triangle? Round to the nearest tenth. Area of a triangle = 1/2 bh
1 answer:
Two ways to find the base
sin(23) = x/30
x = 30*sin(23) = 11.7
or pythagorean theorem
base = 30^2 - 27.6^2 = 11.7
A = 1/2(11.7)(27.6) = 161.5 cm^2

Answer:
9.74 feet
Step-by-step explanation:
the formula for finding a hypotenuse is 
. We can rearrange that to get: 
. So: 49 + b^2 = 144. We get the square root of 95, AKA around 9.74.
Answer:
Solution given:
sin y = -4/5
p/h=4/5
p=4
h=5
b=√{5²-4²)=3
cos y = b/h=-3/5
again
cos x=12/13
b/h=12/13
b=12
h=13
p=√(13²-12²)=5
sin x=p/h=5/13
now
sin[x-y]=sinxcosy-cosxsiny
=5/13×-3/5-(12/13×-4/5)=33/65 is your answer.
