Because
Answer: 3
Step-by-step explanation:
We know that p(t) = 11:
11=2t+5
11-5=2t
6=2t
6/2 = t
3 = t

Answer:
128degrees
Step-by-step explanation:
Note that the given triangle ABC is an isosceles triangle with base angles equal, hence;
m∠BAC = m∠BCA
7x+1 = 5x+9
7x - 5x = 9-1
2x = 8
x = 8/2
x = 4
m∠BAC = 5x+6
m∠BAC = 5(4)+6
m∠BAC = 26 degrees
The vertex angle = 180 - (26+26)
The vertex angle = 180 - 52
The vertex angle = 128degrees
