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

Y=mx+b
|x| because just Google it if I'm wrong
The answer of this math question is C) X= -0.2
Alright so
Surface area = (width x height) + (length x width) + (length x height) + (length x side)
