You need to draw the triangle DEF with a right angle at E. Angle D = 40 and DE = 100 m. Once you have marked up your triangle, you can use cosine to find DF.
Hello,
Let's assume a the hypotenuse
b/a=sin 30°==>b=a/2
c/a=cos 30°==>c=√3 / 2 *a
(√3/2 a, a/2,a) are the sides of the triangle.
7+x^3. It cannot be simplified further without knowing the value of x
Answer:
60
Step-by-step explanation:
So you first start off with 13 and 8 you subtract it and get five so he uses 5 every time he gets paid and you subtract 5 from 65 and get 60
