Answer: D. 9.4 units
Explanation: We use the Pythagoras theorem because we know that it’s a right triangle and we have 2 lengths.
8^2+5^2= c^2
89=c^2
c= sqrt 89
c≈9.4 units
Answer:
B
Step-by-step explanation:
Answer:
76.75 is 25% of 307
Step-by-step explanation:
Write it as an equation:
X - 10 = 6x + 3
Now solve for x:
Subtract 3 from both sides:
x-13 = 6x
Subtract 1 x from both sides:
-13 = 5x
Divide both sides by 5:
x = -13/5
If d₁ and d₂ are the lengths of the diagonals, the area is given by
.. A = (1/2)*d₁*d₂
.. A = (1/2)*(12 in)*(16 in)
.. A = 96 in²
If b is the base and h is the height, the area is given by
.. A = b*h
We know the values of A and b, so
.. 96 in² = (10 in)*h
.. (96 in²)/(10 in) = h = 9.6 in
The height is 9.6 in.
