Answer:
D) 57.5°
Step-by-step explanation:
As the question is not complete. So, let's suppose it is a right angle triangle then, we can apply Pythagoras theorem to calculate the hypotenuse or the third side.
Pythagoras Theorem = =
a = 7 and b = 11
= 49
= 121
Plugging in the values, we will get:
= 49 + 121
= 170
c =
To calculate the unknown angle B, we can use law of sine.
Law of sine = = =
So,
=
=
Sin90 = 1
sinB =
B = ()
B = 57.5°
Multiply everything by 2 then combine like terms
The answer is 8 it should be
Answer:
P = 54 so
arc AC = 150
Step-by-step explanation:
You cant factor by 9 because 15 cant be factored by 9. you can factor it by 5 and get 18x - 3 might want to check my answer
