Help me pls its Pythagorean theorem I need help
ankoles [38]

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

raketka [301]

Answer:

Middle: 2.5  ft

Right: 4,375  ft

Left: 1,875 ft

Step-by-step explanation:

We know that a tree in the middle is 2.5 feet tall.

Now the tree on the left measures 3/4 of the tree in the middle, therefore:

2.5 * 3/4 = 1.875

Which means that the tree on the left is 1.875 feet tall.

Finally the tree on the right 1 3/4, which would be 1.75 times the tree in the middle, therefore:

2.5 * 1.75 = 4.375

Therefore the tree on the right is 4.375 feet tall.
