Answer:
12 cm
Step-by-step explanation:
Well first we can cut the triangle in half and use the Pythagorean theorm
a^2+b^2=c^2
In this case we are going to be doing c^2-a^2=b^2
10^2-8^2=b^2
(10*10)-(8*8)=b^2
100-64=b^2
36=b^2
Now we just square root 36 (what number times itself is 36)
b=6
Since half of the one side equals 6 (DC) then the length of AC is 12!
Answer:
hey mate here is your answer...
Step-by-step explanation:
by using Pythagoras theorem...
<h3>BC² = BD² + DC²</h3><h3 /><h3>10² = 8² + DC²</h3><h3 /><h3>DC² = 100 - 64</h3><h3 /><h3>DC² = 36</h3>
<h2><u>DC = 6</u></h2><h2 /><h2 /><h2><u>DC </u><u>is </u><u>the</u><u> </u><u>half</u><u> </u><u>of </u><u>AC.</u></h2><h2 /><h2><u>Therefore</u><u> </u><u>AC </u><u>=</u><u> </u><u>1</u><u>2</u><u> </u><u>centimetres</u><u>.</u></h2>
<u>hope</u><u> it</u><u> helps</u><u> you</u><u> ❣️</u>

Answer:Thus, (-3)-4 = 1/(-3)4.
Step-by-step explanation:
Negative exponents have the following property: n-m = 1/nm OR 1/n-m = nm
So for (-3)-4 , n= -3 and -m= -4 (or m= 4).
Thus, (-3)-4 = 1/(-3)4.
I think the answer is T equals Q
