Answer:
<h2>7.25</h2>
Step-by-step explanation:
I gave you the answer earlier too!
for more info !
<h2>there s a theorem called MIDPOINT THEOREM </h2>
Which means the 3rd side of the triangle is equal to 1/2 of the line drawn by joining the mid points
<h2>so AB=1/2of YZ</h2>
which means
2x-4 = 1/2×21
thus, 2(2x-4) =21
=> 4x-8 = 21
4x = 29
<h2>x= 29/4 = 7.25</h2>
Statements are all TRUE
sinA =
and cosB = 
cscA = 1/sinA = 1/(a/c) =
and secB = 1/cosB = 1/(a/c) = 
tanA =
and cotB= 1/tanB = 1/ (b/a) = 
<span>3/4x - 4/5 = 1/2x + 1
</span>3/4x - 4/5 = 2/4x + 1
3/4x - 2/4x = 1 + 4/5
1/4x = 9/5
x = (9x4) / (5x1)
x = 36/5
x = 7 1/5
Answer:
36 and -1/8
Step-by-step explanation:
x^2 = 3^2 = 9 * 4 = 36
y^-3 = (-2)^-3 = -1/8
