EGF= 65 CGF= 115 since one angle is 50 and a triangle is 180 you subtract the 180 by 50 and get 130 which you divide by two to get two angles since they r the same
Answer:
x = 42.5
Step-by-step explanation:
Since the triangle is isosceles then the 2 base angles are congruent.
The base line is a straight angle hence the base angle is
180 - 3x
The sum of the 3 angles in the triangle = 180°, hence
2x - 10 + 180 - 3x + 180 - 3x = 180
- 4x + 350 = 180 ( subtract 350 from both sides )
- 4x = - 170 ( divide both sides by - 4 )
x = 42.5
-------------------------------------------
2x - 10 = (2 × 42.5) - 10 = 75
180 - 3x = 180 - (3 × 42.5) = 52.5
Sum of 3 angles = 75 + 52.5 + 52.5 = 180° ← correct
where m is the slope of the line and b is the y-intercept. Hope that helps
The answer is B because the slope is always the number next to t x and the y intercept is the other number.
