Answer:
A cos C = 12/13
Step-by-step explanation:
cos theta = adjacent side/ hypotenuse
cos C = BC/AC
But we don't know BC, but we can find it using the Pythagorean theorem
a^2 +b^2 = c^2
5^2 +BC^2 = 13^2
25 + BC ^2 =169
Subtract 25 from each side
BC^2 = 169-25
BC ^2 = 144
Taking the square root of each side
BC =12
cos C = 12/13
Answer:
7.3
Step-by-step explanation:
D-75÷8=2
P.E.M.D.A.S
parenthesis, exponents, multiplication, division, addition, subtraction
Which on comes first would be
Division
75÷8= 9.3-D=2
9.3
-2.0
-----
7.3
So, D would equal 7.3.

<h2>
Answer:</h2>
7.5cm2
<h2>
Step-by-step explanation:</h2>
5x3cm=15cm2 because of base x height/2 you would do
15cm2 divided by 2 since it is a triangle (a half of a square) which is 7.5cm2
