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°
Vector

.

. So the sum is

.
For the second, the magnitude is the square root of the sum of the squares of the components. This is equal to

.
In order from left to right its RRRT
R is repeating and T is terminating

Step-by-step explanation:
Number of marbles = 400
Anthony sells 1/4 of the marbles to Jayveon. This will be:
= 1/4 × 400
= 100 marbles
Anthony gives 10% to Abdul. Abdul will have:
= 10% × 400
= 0.1 × 400
= 40 marbles
He gave 10 marbles to his little brother.
The number of marbles that Anthony has left will be:
= 400 - (100 + 40 + 10)
= 400 - 150
= 250 marbles
