Answer:
180 cm
Step-by-step explanation:
2(3*10) = 60
3*12 = 24
1/2(12*8) * 2 = 96
formula for a triangle is 1/2 b h
Answer:
Its D, 5 4/9
Step-by-step explanation:
So you can turn them into improper feactipons if it’s hard at first (I can already do it without turning them into improper so it’s asker for me)
so 19/9-2/9+32/9
Now add them like you normally would since all the denominators are the same.
you’ll get 49/9
now just simplify that into a mixed mnumber
5 4/9
Answer:
between g and h
Step-by-step explanation:
Answers:
cos(A) = 0.8480
tan(B) = 1.6
=============================================
Explanation:
Before we can compute cos(A), we'll need to find the hypotenuse.
Use the pythagorean theorem.
a^2 + b^2 = c^2
8^2 + 5^2 = c^2
89 = c^2
c^2 = 89
c = sqrt(89)
The hypotenuse is exactly sqrt(89) units long.
This will allow us to find the cos(A) value
cos(angle) = adjacent/hypotenuse
cos(A) = AC/AB
cos(A) = 8/sqrt(89)
cos(A) = 0.84799830400509 which is approximate
cos(A) = 0.8480 when rounding to four decimal places
-------------------------
For the tangent ratio, we won't use the hypotenuse. Instead, we use the opposite and adjacent sides like so:
tan(angle) = opposite/adjacent
tan(B) = AC/BC
tan(B) = 8/5
tan(B) = 1.6
