The biking portion of the triathlon is 11.7 miles far

Step-by-step explanation:

Let us revise the relation between the two legs of a right triangle and

the hypotenuse

Hypotenuse = \sqrt{(leg_{1})^{2}+(leg_{2})^{2}}

To find the length of the hypotenuse

1. Square the length of each leg

2. Add the squares of the legs

3. Find the square root of the sum

∵ The legs of the triangle consist of a 4 mile  swim and a 11 mile run

∴ leg_{1} = 4

∴ leg_{2} = 11

∵ ( leg_{1} )² = (4)² = 16

∵ ( leg_{2} )² = (11)² = 121

∴ ( leg_{1} )² + ( leg_{2} )² = 16 + 121 = 137

∵ The hypotenuse of  the triangle is the biking portion of the  event

∵ Hypotenuse = \sqrt{(leg_{1})^{2}+(leg_{2})^{2}}

∴ Hypotenuse = \sqrt{137} = 11.7

The biking portion of the triathlon is 11.7 miles far

∠QPS is a right angle and m∠QPR = 71°, what is m∠RPS?
natta225 [31]

Answer: <RPS = 161

Step-by-step explanation:

P is the common vertex in all of these angles. From this we know that these have to be adjacent angles (<QPR and <QPS) that equal the whole angle (<RPS)

<QPR+<QPS= <RPS

71+90= 161

(<QPS is a right angle. Right angles are equal to 90 degrees.)

Find the equation of a line perpendicular to -x=4-y that passes through the point (-3,8)
Wewaii [24]

9514 1404 393

Answer:

  y = -x +5

Step-by-step explanation:

Solving the given equation for y, we have ...

  y = x +4

The slope of this line is the coefficient of x: 1. The slope of the perpendicular line will be the opposite reciprocal of this: -1/1 = -1. The y-intercept of the perpendicular line can be found from ...

  b = y -mx = 8 -(-1)(-3) = 5

The perpendicular line has equation ...

  y = -x +5

Cole says that all quadrilaterals are polygons but not all polygons are quadrilaterals is he correct explain������
zepelin [54]
YES, this is correct. All quadrilaterals whether is a trapezoid, parallelogram, rhombus and others, they are all polygons and all they have 4 sides and 4 angles. We know that a polygon is a figure with at least three sides and three angles.

Not all polygons are quadrilateral, this is also correct since some polygons have five or more sides and angles.
