Since base angles of an isosceles triangle are congruent the other base angle is also 65. since the three angles together sum to 180 thst leaves 180-65-65=180-130 = 50 degrees for the vertex angle
The answers are:
A) right triangle
B) right triangle
C) right triangle
Answer:
first is 3.5, second is 1
Step-by-step explanation:
-4.5 = x + 2x - 6
-4.5 - 6 = 3x
10.5 = 3x
10.5/3 = x
3.5 = x
2(3.5) - 6
7 - 6
