Answer:
the answer is 3.81
but rounding it it will be 3.8 meters
Step-by-step explanation:
Pythagorean theorem says
a²+b²=c²
so,
take take the Lowest measurement as a² which will be 7 and take 8 as the hypotenuse or the longest side which is c²
then put it all together you get
7²+x²=8²
we made b as x because we will be finding b
then substitute the values
x²=8²-7²
x²=64-49
x²=15
to remove that square from the x you then put square root in both
✓x²=✓15
press in the calculator, root of 15 will be about 3.81
now we got
x=3.81
x is the missing measurement
You have to make the denominators(bottom of the fraction) the same in order to combine the fractions.
To make the denominator of 
the same as 
, you multiply the top and bottom of the fraction by 2 (because they both have a common multiple of 4)
So:
Answer:
a) 1/2, 1/2, 1/2
b) T
R
S
c) DEF and TRS are similar
Step-by-step explanation:
a) TR/DE = 9/18 = 1/2
RS/EF = 8/16 = 1/2
TS/DF = 5/10 = 1/2
b) E is the smallest angle on the DEF, and it corresponds w the smallest angle on TRS, R. D corresponds to T, and F to S
they r similar figures - u can see it if u tilt TRS counterclockwise nd flip it
c) they r similar bcuz u can see in part a) that they all have proportional side lengths so yea theyre similar
