Answer:

$\sqrt{39}$

Step-by-step explanation:

I think the answer choices were supposed to be:

$\sqrt{3} , \sqrt{6} , \sqrt{39} , \sqrt{89}$

Pythagorean Theorem: a²+b²=c²

5²+b²=8²

25+b²=64

Subtract 25 from both sides

b²=39

Square root both sides

b= $\sqrt{39}$

Our answer is $\sqrt{39}$

The measure of ∠FHJ is 60°. The measure of ∠FGH is 28°. What is the measure of ∠HFG?

Hatshy [7]

Given
∠FHJ = 60°
∠FGH = 28°

∠FHG = 180 - ∠FHJ
∠FHG = 180 - 60
∠FHG = 120

∠HFG = 180 - (28 + 120)
∠HFG = 180 - 148
∠HFG = 32

salantis [7]

Answer:

<-6,-4>

Step-by-step explanation:

To find u+v, all you have to do is add the corresponding components of each.

That is for example on this problem, you would do

<-3,-5>+<-3,1>

=<-3+-3,-5+1>

=<-6,-4>.
