Answer:
yes , 33^2 + 56^2 = 65^2 and obtuse
Step-by-step explanation:
<h2><u>Question 3</u></h2>
make use of the Pythagoras theorem
which is :
c^2 = a^2 + b^2
where c is the hypotenuse.
now put the values in the equation
65^2 = 56^2 + 33 ^2
the answer is :
<u>yes , 33^2 + 56^2 = 65^2</u>
<u></u>
<h2><u>Question 4</u></h2>
<u />
note if :
c^2 = a^2 + b^2 ----------- right
c^2 < a^2 + b^2------------ acute
c^2 > a^2 + b^2------------- obtuse
hence :
16 + 30 > 38
therefore its : <u>obtuse </u>
Answer:
Each pair of shoes cost 26$
Step-by-step explanation:
<em>find the total cost for shirts</em>
2 shirts * 12$ each
2 * 12 = 24
they spent 24$ on shirts
<em>create an equation</em>
24$ shirts + x$ shoes = 76$
24 + x = 76
<em>subtract 24 from both sides of the equation</em>
24 + x - 24 = 76 - 24
x = 76 - 24
x = 52
they bought 2 pairs of shoes that cost the same amount
52 = x + x
52 = 2x
<em>divide both sides of the equation</em>
52/2 = 2x/2
52/2 = x
26 = x
each pair of shoes cost 26$
(n+7)2
= (n)(2) + (7)(2)
=2n+14
