Answer:

x = 15.2

Step-by-step explanation:

you can use the Pythagorean Theorem on either half of the large triangle because you know one leg is 29/2 and the hypotenuse is 21

(29/2)² + x² = 21²

210.25 + x² = 441

x² = 230.75

x = $\sqrt{230.75}$

x = 15.2

Fishman
Goron
Smith
Other

3(b):

(280 × 35) ÷ 100 = 98 people.

3(c):

No, because the ratio of 'Other' to 'Goron' is 1:3.5, and if 40 people voted for other, then that means 140 people should've voted for Goron, but only 98 people did, therefore the estimate wasn't accurate.

Answer:

$x=138$

Step-by-step explanation:

So we have the equation:

$\sqrt{x+6}+5=17$

First, let's determine the domain restrictions. Recall that the radicand cannot be negative. In other words, it must be greater than or positive than 0. Thus:

$x+6\geq 0$
