Find angle <QPS in the diagram​

Mathematics
1 answer:
marin [14]3 years ago
4 0

Answer:

40°

Step-by-step explanation:

Because triangle QSR is isosceles ∠SQR=∠SRQ=35°. The sum of the angles in a triangle is 180°, so ∠QSR=180°-35°-35°=110°. The measure of a straight line is 180°, so ∠PSQ=180°-110°=70°. Because triangle PSQ is also isosceles ∠PSQ=∠PQS=70°. Then, ∠QPS=180°-70°-70°=40°.

Which best describes the angles of some parallelograms? A. Four obtuse angles B. Four acute angles C. Two acute and two obtuse a
anyanavicka [17]
Some parallelograms have 2 obtuse and 2 acute angles.  

Parallelograms may have all 90 degree angles as well.  These are also called rectangles.  

When you "bend" a rectangle it naturally forms 2 acute and 2 obtuse angles.

If a=5x^2+3x-7 and b=-3x^2-7x+5 find b-a
uranmaximum [27]

Answer:

-8x^2-10x+12

Step-by-step explanation:

first set up the problem:

(-3x^2-7x+5)-(5x^2+3x-7)

Since you are subtracting you need to distribute the (-) sign:

(-3x^2‐7x+5)(-5x^2-3x+7)

Now just combine like terms

-3x^2+(-5x^2= -8x^2

(-7x+(-3x= -10x

5+7= 12

set answer in standard form:

-8x^2-10x+12

For a certain race, 3 teams were allowed to enter 3 members each. A team earned 6 – n points whenever one of its members finishe
ololo11 [35]

Answer:

The least possible score a team could have earned is 3.

Step-by-step explanation:

From the given information it is clear that the total number of teams is 3.

Total number of members in each team is 3.

A team earned 6 – n points whenever one of its members finished in nth place, where 1 ≤ n ≤ 5.

It means the points for 1st, 2nd, 3rd, 4th, and 5th place are 5, 4, 3, 2 and 1 respectively.

Total points that can be earned all teams together = 5+4+3+2+1=15

There were no ties, disqualifications, or withdrawals.

To minimize the score of a team, we have to maximize the score of the other two teams.

It is given that no team earned more than 6 points,

Let two teams earn there maximum score. i.e. 6. So the score of third team is

15-6-6=3

Therefore, the least possible score a team could have earned is 3.
