Answer:

So here is how we are going to get the measure of angle 2.

Since given that angle COE measures 55°, we will equate m∠2 = 2x and m∠3 = x+10 with 55. So, 55 = 2x + x + 10

55 = 3x + 10

55-10 = 3x

45 = 3x << divide both sides by 3 and the result is

15 = x

So now that we know x, we can now solve for angle 2.

m∠2 = 2x

m∠2 = 2(15)

m∠2 = 30°

I hope that this is the answer that you are looking for.

If a =5, 0, −1,find a vector b such that compab = 2.b = _______.

Arturiano [62]

Answer:

$b = (q,r , 5q-2\sqrt{26} )$

Step-by-step explanation:

From the question we are told that

The vector given is

$a = (5,0,-1)$

Also $comp_a b = 2$

Generally

$comp_a b = \frac{a \cdot b}{|a|}$

Here $|a|$ is the magnitude of a which is mathematically represented as

$|a| = \sqrt{5^2 + 0^2 +(-1)^2 }$

=> $|a| = \sqrt{26}$

b is vector which we will assume to have the following parameters

$b = (q , r , x)$

$comp_a b = \frac{(5,0,-1) \cdot (q,r,x)}{\sqrt{26} } = 2$

=> $\frac{5q + 0 -x}{\sqrt{26} } = 2$

=> $x = 5q-2\sqrt{26}$

Hence the vector be can be mathematically represented as

$b = (q,r , 5q-2\sqrt{26} )$

This means that the vector b is more than one value since it is made up of variable

This means that if

$q = 1\\r=1\\x =1$

Then

$b = (1,1,5-2\sqrt{26} )$
