What is the slant height x of the square pyramid? Enter your answer in the box, express your answer in radical form.

Nadya [2.5K]

<span> For this case we have a rectangle triangle where we know:
hypotenuse of the triangle.
Angle between the base of the triangle and the hypotenuse.
We want to find the height of the triangle.
For this, we use the following trigonometric relationship:
</span> $sine (60) = x / 8
$
<span> From here, we clear the value of x.
We have then:
</span> $x = 8 * sine (60)

x = 6.93 m$ <span>
Answer:
The inclined height of the pyramid is given by:
x = 6.93 m</span>

Find the equation of a line passing through a point (3,5) and perpendicular to the line joining the points (3, 7) and (7, -1)

eduard

Step-by-step explanation:

we start first by finding the gradient of the line

change in y/change in x

7-(-1)/3-7=8/-4

=-2

then for perpendicular lines m1m2=-1

therefore to find the gradient of that line

-2m2=-1

therefore m2=2

so therefore

y-5/x-3=2

so y-5=2x-6

y-2x=-1

in the form y= mx +c

then y=2x-1

Name the missing coordinate(s) of each triangle

Cloud [144]

Answer:

13) C (a, a) Y (a, 0)

14) B (0, b) P (a, 0)

Step-by-step explanation:

13) Y lies on x axis so it is Y(a,0)

ZY = YC = a

so for C coordinates are (ZY,YC) = (a, a)

14) B lies on y axis so it is B(0, b)

BK = BP = $\sqrt{a^{2} + b^{2} }$ = distance between two points

so P is (a, 0) as it is same distance and on positive side of x axis
