A=61 since if you do the opposite equation 42+19=61
The magnitude of the vector is

the component form is
<2,5>
76÷4= ; x=19, you divide 76 by 4 because if he is 1/4 then it would be a group of one of the 4's, thus saying ehen you divide 76 by 4, it equals 19, so he is 19 years old, you could also do 19×4 and 22×4 to see which equals 76.
Answer:
This is a 45-45-90 right triangle
So we know that because at least one angle is 45 degrees and there is a right angle.
A 45-45-90 triangle has congruent (equal) legs {x} and the hypotnuse is
x√2
So using that information we know X = Y
Since they are both legs and legs are congruent in this case.
The hypotnuse is laid out for us which is 8.
We can make an equation.
Since the hypotnuse would be x√2
x√2 = 8
Now we solve.
You’d get 5.6528… or √32
X and Y both equal √32
