Ответ:
x = 98
Step-by-step explanation:
This is simple. It's an exterior angle.
We already have the angles that make up an exterior angle.
45 and 53.
So we just add it according to the rule.
So, it's 98.
You can also check this by finding the missing angle of the triangle.
So we know that 98 is for the first two angles and now we subtract that from 180 to find the missing angle of the triangle.
We get 82
So then since a line is 180 degrees, we subtract 82 from 180 to get x which is 98.
So your answer is still 98

Step-by-step explanation:No , theres not enough information provided to Prove that both the triangles are congruent. Here in the figure we can see that there are two triangles ∆ BDA and ∆ BDC. And its given that
AB = BC BD = BD ( common side )The congruence conditions for two ∆s are :-
1) SAS ( Side Angle Side )
→ Two triangles are said to be congruent by SAS if two respective sides of the two triangles and the included angle between two sides are equal.
2) AAS ( Angle Angle Side )
→ Two triangles are said to be congruent by AAS if two angles and one side of triangle is congruent to other two angles and one side of the triangle .
3) SSS ( Side Side Side )
→ Two triangles are said to be congruent by SAS if all the three sides of one triangle is equal to three sides of the other triangle.
4) RHS ( Right Hypotenuse Side )
→ In two right-angled triangles, if the length of the hypotenuse and one side of one triangle, is equal to the length of the hypotenuse and corresponding side of the other triangle, then the two triangles are congruent.
And the given data doesn't satisfies any of the conditions.
Hence there is not enough information provided to Prove that two triangles are congruent .
