Step-by-step explanation:
Answer:
Step-by-step explanation:
B. Yes, because it passes the vertical line test, is the answer.
The three inside angles of a triangle need to equal 180 degrees.
To find X subtract the two known angles from 180.
X = 180 - 45 - 70
X = 65 degrees.
Answer:
The base angles are 36° each
Step-by-step explanation:
An isosceles triangle is a triangle that has two of its sides and base angles to be equal.
If an isosceles triangle has a vertical angle of 108°, then the base angles will share the remaining angle in the triangle equally.
Since the sum of angles in a triangle is 180°
The remaining angle in the triangle = 180°-108°
= 72°
Since the base angles are equal, this remaining two angles will share angle 72° equally.
The base angles = 72°/2
The base angles = 36°
This shows that the base angles are 36° each.
