Explain how you would find the perimeter of this triangle.

Mathematics
1 answer:
Lynna [10]2 years ago
4 0

Answer:

<em>15.4 </em>

Step-by-step explanation:

\frac{u}{4} = tan51.3° ⇒ u = 4tan51.3° ≈ 5

\frac{4}{v} = cos51.3° ⇒ v = \frac{4}{cos51.3} ≈ 6.4

<em>P </em>≈ 4 + 5 + 6.4 = <em>15.4</em>

The area of a triangle is 1/2 of base times height
for ΔPQS, the base is PS=6, the area is 16.5, so the height is 16.5×2÷=5.5
the height of the triangles is also the height of the trapezoid.

what is an equation of the line that is parallel to y equals negative 4x - 5 and passes through the point -2, 6
Bond [772]

y = - 4x - 2

the equation of a line in slope-intercept form is

y = mx + c ( m is the slope and c the y-intercept )

y = - 4x - 5 is in this form

with slope m = - 4

• Parallel lines have equal slopes

y = - 4x + c ← is the partial equation

To find c substitute (- 2, 6 ) into the partial equation

6 = 8 + c ⇒ c = 6 - 8 = - 2

y = - 4x - 2 ← equation of parallel line
