Hello!
All of the interior angles of a triangle add up 180°. As we already have two of our angles, we can subtract them from 180 to get our angle.
180-70-45=65
Therefore, our answer is B) x=65°.
I hope this helps!
The required value of angle x is 65° for the given triangle. Option B is correct.
Given that,
A figure of the triangle has shown, with interior angles ∠ A = 45°, ∠ B = 70°, and ∠ C = x.
The value of the x is to be determined.
The triangle is geometric shape that includes 3 sides and the sum of interior angles should not be greater than 180°
The angle can be defined as the one line inclined over another line.
Here, the sum of the interior angle of a triangle is 180°
So,
∠ A + ∠ B + ∠ C = 180°
45 + 70 + x = 180
x = 180 -115
x = 65
Thus, the required value of angle x is 65° for the given triangle. Option B is correct.
