Answer:

Step-by-step explanation:
The triangle is a right triangle.
We can use trigonometric functions to solve the problem.
tan θ = opp/adj
tan 30 = y/(4√3)
y = 4√3 tan 30
y = 4
The standard form of 6x1x5x1/10 =3 x 10 ^0, any number raised to the power of 0 is 1 so 1 x 3 = 3
Answer:
Perpendicular lines are lines that intersect at a right (90 degrees) angle
Step-by-step explanation:
Answer:
b=-a
Step-by-step explanation:
we know that b is located the same distance from 0 as another number, a, but in the opposite direction.
so the sum of the two numbers equal zero
a+b=0
a=-b or b=-a
