If x is an obtuse angle, then what is true for x?

Correct Answer: 90° < x < 180°
An obtuse angle always measures between 90° and 180°, therefore the value of an acute angle is always between 90° and 180°. In the diagram given below, ∠PQR is an obtuse angle whose value is greater than 90° and less than 180°.

In a scissors cross-over, the crossings provided are
i) 2 obtuse angle crossings
ii) 4 obtuse angle crossings
iii) 4 acute angle crossings
iv) 6 acute angle crossings
The correct answer is

A series is given with one term missing. Select the correct alternative from the given ones that will complete the series. Acute angle, right angle, obtuse angle, ?

From an alloy, two specimens are machined and tested separately under tension and compression. The engineering stress-strain curves as well as the true stress-true strain curves for tension and compression are plotted in the same diagram. Identify the correct statements:
P. The engineering stress-strain curves in tension and compression are identical.
Q. The true stress-true strain curve in compression is lower than the true stresstrue strain curve in tension due to Bauschinger effect.
R. The true stress-true strain curve in tension is above the corresponding engineering stress-strain, curve.
S. The true stress-true strain curve in tension and compression are identical.

In ΔABC, ∠C is an obtuse angle. The bisectors of the exterior angles at A and B meet BC and AC produced at D and E respectively. If AB = AD = BE, then ∠ACB = ?

What is the area of an obtuse angled triangle given below with two sides are 8 and 12 and the angle included between two sides is 150 deg?

What is the obtuse angle formed by the hands of a clock when the time in the clock is 2:30?

The smallest angle of a triangle is 40° less than the largest angle. If the largest angle is 80°, then find the third angle of the triangle

A retaining wall 6m high supports a backfill with a surcharge angle of 10°. The back of the wall is inclined to the vertical at a positive batter angle of 5°. If the angle of wall friction is 7°, then the resultant active earth pressure will act at a distance of 2 m above the base and inclined to the horizontal at an angle of
