In the parallelogram PQRS

PS = 5 and ∠Q = 105

<h3>What is defined as the parallelogram?</h3>

A parallelogram is a type of quadrilateral created by parallel lines.
A parallelogram's angle between adjacent sides can vary, however the opposite sides must be parallel in order to be a parallelogram.
A parallelogram is formed when the opposite sides of a quadrilateral are parallel as well as congruent.

For the given question;

In the parallelogram PQRS,

QR = PS = 5 (opposite side of parallelogram are parallel and equal).

Sum of all angles is 360.

∠Q = ∠S (opposite angles of parallelogram are equal)

∠P + ∠Q + ∠R + ∠S = 360

2∠P + 2∠Q = 360

2∠Q = 360 - 2∠P

2∠Q = 360 - 150

2∠Q = 210

∠Q = 105

Thus, the angle Q is found as 105 degrees.

$\purple{\maltese}\large\underline{\underline{\red{\sf\:\: Given :}}} \\$

Mass (M) of space shuttle = 1.0 × 105 kg.
Altitude (r) = 200.0 km

$\\\purple{\maltese}\large\underline{\underline{\red{\sf\:\: To \: \: Find :}}} \\$

The force of gravity that the space shuttle experiences = ?

$\\\purple{\maltese}\large\underline{\underline{\red{\sf\:\: Solution :}}} \\ \\$

$\purple{\maltese}\large\underline{\underline{\sf\:\: using \: formula :}} \\ \\$

$\bigstar \: \underline{ \boxed{\sf { \pink{g = \frac{G \: M}{{r }^{2} }}}}} \\ \\$

$\\ ❒\: \: \underline{\textbf {Putting values \: in \: the \: \: given \: formula :}} \\$

$\sf \implies \: g = \frac{G \: M}{{r }^{2} } \\$

$\sf \implies \: g = \frac{6.67×10^{-11} × 1.0×10^5}{(2×10^5)^{2} } \\$

$\sf \implies \: g = \frac{6.67×10^{-6}}{4×10^{10}}\\$

$\sf \implies \: g = \frac{6.67×10^{-6}}{4×10^{10}} \\$

$\sf \implies \: g =1.6675×10^{-6-10}\\$

$\sf \implies \: g =1.6675×10^{-16}\: Newton\\\\$

$\:\:\:\:\:\:\:\qquad\rule{150pt}{2pt} \\\\$

Henceforth, the force of gravity experienced by the shuttle is <u>1.6675×10^N</u>

Someone please help me <br> Find the value of x .<br> A) 80 <br> B) 100<br> C) 130 <br> D)120

zzz [600]

130 +145 +65+160+120 = 620

the total inside angles for a 6 sided polygon should = 720

so x = 720-620 = 100

B is the answer

Plot two points that are 3units from Point C and also share the same y-coordinate as Point C.

egoroff_w [7]

The two points at a distance of 3 units from C with the same y coordinate are (-3, -5) and (-9, -5).

Step-by-step explanation:

Step 1:

First, we must plot the point C on the graph. Point C is on the third quadrant so the x value and the y value are negative.

The coordinate of C is (-6, -5).

We need to plot two points that are 3 units away from point C but have the same y coordinate i.e. y = -5.

Step 2:

So assume the two other points are A and B.

The y coordinates of A and B are -5. Only the x coordinate varies. So in order to get the coordinates of point A and B, we add and subtract 3 from the x coordinate of point C.

Point A = (-6+3, -5) = (-3,-5).

Point B = (-6-3, -5) = (-9, -5).

So two points at a distance of 3 units from C with the same y coordinate are (-3, -5) and (-9, -5).
