Answer/Step-by-step explanation:
The missing length can be found by applying pythagorean theorem. Thus:
Missing length = √((8x)² - (2x)²)
Missing length = √(64x² - 4x²)
✔️Missing length = √(60x²) = 2x√15
Plug in the value of x which is 3
Missing length = 2*3√15
✔️Length = 6√5
since it is perpendicular line you have to change thing signs of the equation.
x y
(-1,4)
replace the (-1) with x and (4) with y
y=1/2x+b
4=1/2(-1)+b
4=-1/2+b
4+1/2=b
9/2=b
therefore, the perpendicular line is y=1/2x+9/2
Answer:
100 + 40 + 40 + 40 + 40
Step-by-step explanation:
area of base = 10 x 10 = 100 square units
area of each triangular side = 0.5 x 10 x 8 = 40 square units.
Total area = 1 base + 4 sides
= 100 + 40 + 40 + 40 + 40
