Answer:
The correct option is 4. The measure of arc PQR is 220°.
Step-by-step explanation:
Given information: PQRS is a quadrilateral and the measure of angle PQR is 70 degrees.
According to the central angle theorem, that the angle inscribed on the circle is always half the measure of the central angle.
Using central angle theorem,
The measure of of arc PQR is
Therefore the measure of arc PQR is 220°. Option 4 is correct.
Answer:
.
Step-by-step explanation:
We know that if two corresponding sides of two triangles are equal, then third sides of the triangles depend on angle between equal sides.
Angle opposite to larger side is larger.
Since, 14 < 15, therefore
...(1)
We know that, angle can not not negative.
...(2)
From (1) and (2), we get
Therefore, the range of values of x is .
Answer:
No, it is not a right triangle.
Step-by-step explanation:
Given:
The sides of the triangle = 15 10 and 7
To Find:
Whether the triangle is a right triangle = ?
Solution:
According to Pythagorean theorem , In an right triangle the the sum of the squares of the two smaller sides must equal to the square of the larger side
where
a and b are the smaller sides
c is the larger side
Now from the given data, lets assume
a = 10 and b =7 and c =15
Substituting in the above equation we get,
100 + 49 = 225
149 = 225
So, the given triangle is not a right triangle.
