Answer:
½ - sqrt(3)
Step-by-step explanation:
cos(60) = ½
tan(30) = 1/sqrt(3)
cot(30) = sqrt(3)
tan(90) is undefined
cot(90) = 0
½ - sqrt(3) -0
½ - sqrt(3)

Answer:
A
Step-by-step explanation:
Hey There!
So these triangles are congruent so segment CD is equal to segment DB
so to find x we use the equation
7x+10=10x+7
now we solve for x
step 1 subtract each side by 7
10-7=3
7-7 cancels out
now we have 7x+3=10x
step 2 subtract each side by 7 x
10x-7x=3x
7x-7x= cancels out
now we have
3x=3
step 3 divide each side by 3
3/3=1
3/3 cancels out
now we have
x=1
