dy/dx= sin(x+y) +cos(x+y) evaluate differential equation.
Answers
Answer:
A triangle ABC is given .
The measurement of angle A = 70
The measurement of angle C = 140
Let the angle B be x
\implies\:70 \:+\: x\: = \:140⟹70+x=140 ( by exterior angle property )
\implies\:x \:= \:140\: -\: 70⟹x=140−70
\implies\:x \:= \:70⟹x=70

⋆EXTERIOR ANGLE PROPERTY :- An exterior angle of a triangle is equal to the sum of the opposite interior angles.
⋆ANGLE SUM PROPERTY :- Angle sum property of triangle states that the sum of interior angles of a triangle is 180°.
⋆What are the types of triangle?
\implies⟹ An equilateral triangle has three equal sides and angles.
\implies⟹ An isosceles triangle can be drawn in many different ways. 2 sides and 2 angles are equal.
\implies⟹ A right-angled triangle has one 90° angle.
\implies⟹ A scalene triangle has three different angles and none of its sides are equal in length
