Answer:

  -1.131

Step-by-step explanation:

The relationship between secant and tangent is ...

  sec²(x) = 1 + tan²(x)

In the 3rd quadrant, the secant is negative, so the value is ...

  sec(θ) = -√(1 +tan²(θ)) = -√(1 +(1.885/3.572)²) ≈ -√1.278483718

  sec(θ) ≈ -1.131

Perimeter of a triangle is 27cm,if two sides measure 9cm and 7.8cm,find the measure of third side?
fredd [130]

Answer:

10.2cm

Step-by-step explanation:

Perimeter is the sum of the lengths of all sides.

1st side: 9cm

2nd side: 7.8cm

Perimeter: 27cm

Perimeter = 1st + 2nd +3rd side of a triangle

27cm = 9cm +7.8cm + 3rd side

3rd side = 27cm - 9cm -7.8cm

              = 10.2cm

Can anyone explain how you graph things for example, like y=x-4 how would you graph that
Savatey [412]

Answer:

In basicallity if a question such as this pops up, the correct way to go would first be to graph this. y=x-4 would be equivalent to x=4.

My paper work is below:

y = x - 4

0 = x - 4

-x = -4

x = 4

Hope this helped..
