It is possible for a triangle to be both isosceles and obtuse. Then the correct answer is option D.
The triangle in which the two opposite sides are equal and the two opposite angles are equal is called the isosceles triangle.
In the isosceles triangle, if the angles are:-
Triangle ABC, ∠A = ∠B = 30 (isosceles) and ∠C = 120 (obtuse)
Sum of the angle = 30+30+120 = 180
Hence, the correct answer is option D.

It is possible for a triangle to be which of the following?
Answer is:
both isosceles and obtuse
Example:
Triangle ABC, <A = <B = 30 (isosceles) and <C = 120 (obtuse)
Sum = 30+30+120 = 120
will bring the submarine back to sea level (0 feet)?
Answer:
To bring the submarine back to the sea level, it have to move 578 feet upwards
Step-by-step explanation:
Given:
Initially the depth the submarine dives = 657 feet below sea
The height the submarine moves up = 79 feet
To Find :
Change in its depth required to bring the submarine back to the sea level = ?
Solution :
In initially the Submarine will be at the depth of 657 feet below sea
when it goes up, the the depth reduces
657 - 79 = 578 feet
Now the submarine will be the depth of 578 feet
Now the submarine have to move 578 feet upwards to reach the sea level
the answer is x > -2
x is greater then -2 and that is the 3 one
