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
Answer:
240
Step-by-step explanation:
To evaluate 19^2 - 11^2, we have to use a special product pattern. Since this expression is in the form a^2 - b^2, we use the pattern (a + b)(a - b).
Therefore, the answer is 240.

True. Distance formula will give you the length between any two points.
Answer: z = -5/-3
Step-by-step explanation:
(3z−11)+(6−6z)
3z - 11 + 6 - 6z
- 6z + 3z - 11 + 6
- 3z - 5
z = -5/-3
