Hey there! :)
Answer:
C) 74 units.
Step-by-step explanation:
MT is congruent to KT because the diagonals of a quadrilateral bisect each other. Therefore:
8y + 18 = 12y - 10
Subtract 8y from both sides:
18 = 4y - 10
Add 10 to both sides:
28 = 4y
Divide both sides by 4:
28/4 = 4y/4
y = 7 units. Plug this into the equation for MT:
8(7) + 18 = 74 units.
Answer:
16
Step-by-step explanation:
Answer:
4.7 to nearest tenth.
Step-by-step explanation:
By Pythagoras:
8^2 = x^2 + 6.5^2
x^2 = 8^2 - 6.5^2
x^2 = 64 - 42.25 = 21.75
x = √21.75
= 4.6637
