Answer:
11/4
Step-by-step explanation:
tan(90-x)=cot(x) by cofunction identity
tan(90-x) is therefore the reciprocal value of tan(x) since tan(x) is the reciprocal of cot(x) or vice versa.
tan(90-x)=11/4 since tan(x)=4/11
Answer:
106.60 cm^2
Step-by-step explanation:
A triangle is a three-sided polygon with three edges and three vertices. the sum of angles in a triangle is 180 degrees
Area of a triangle = 1/2 x base x height
1/2 x 13 x 16.4 = 106.60 cm^2

Answer:
3
Step-by-step explanation:
10x=1000
Solve Exponent.
10x=1000
log(10x)=log(1000)(Take log of both sides)
x*(log(10))=log(1000)
x=log(1000)log(10)
x=3
