Violeta wants to install new tiling in her kitchen. She places two triangular tiles together as shown in the following figure. I
n order to plan her installation, she needs to find the length of BC
1 answer:
Answer:
25
Step-by-step explanation:
To obtain the length of BC, we shall apply the pythagoras theory as show below:
From the diagram above, the pythagoras theory states as follow:
|BD|² = |CD|² + |BC|²
|BD| = 65
|CD| = 60
|BC| = m
|BD|² = |CD|² + |BC|²
65² = 60² + m²
4225 = 3600 + m²
Collect like terms
m² = 4225 – 3600
m² = 625
Take the square root of both side
m = √625
m = 25
|BC| = m = 25
Therefore, the length of BC is 25

Answer:
D 2+6x
Step-by-step explanation:
-2/3(-3-9x)
(-2/3×-3)+(-2/3×-9x)
6/3+18x/3 = 2 + 6x
Answer:
2i or -2i
Step-by-step explanation:
2x² = -8 First, clear x.
x² = -8/2 Solve
x² = -4 Now, eliminate the square of x by solving the square root of -4.
x = √-4
x = 2i or -2i Is an imaginary number.
