Answer: No .
Step-by-step explanation:
If we make two triangles with lengths of 4 centimeters and 2 centimeters and an included angle of 50°, then by SAS congruence postulate both triangle will be congruent.
According to the definition of congruence , if two shapes are congruent then they have equal size and shape.
i.e. they look exactly same.
It means only one triangle is possible with the given measurement .
- SAS congruence rule : It says that if two sides and the included angle of a triangle are congruent to two sides and the included angle of another triangle, then we can say that these two triangles are congruent.
Hello!
To solve this we can use the Pythagorean Theorem, a²+b²=c², where a and b represent the legs and c represents the hypotenuse. We will solve below.
1²+3²=c²
1+9=10
We have 10=c². We can isolate c by finding the square root of 10.
√10≈3.16
Therefore, the other side could be 3.16.
---------------------------------------
Note that 3 could also be the hypotenuse. We could solve the equation the other way around to see what the other side could be (it could be the hypotenuse or a leg).
9-1=8
√8≈2.83
Therefore, the length of the third side could be either 3.16 or 2.83.
I hope this helps!

Answer:
(b) 60°
Step-by-step explanation:
The sum of angles in a pentagon is 540°, so you have ...
90° +90° +150° +x +150° = 540°
x = 540° -480°
x = 60°
