Answer:
x = 8, y = 4√3, z = 8√3
Step-by-step explanation:
Assuming that y is the altitude of the triangle (perpendicular to the hypotenuse), the triangles are similar. So we can write proportions:
x / 4 = 16 / x
x² = 64
x = 8
4 / y = y / 12
y² = 48
y = 4√3
z / 12 = 16 / z
z² = 192
z = 8√3
Note: after finding one side, you can also use Pythagorean theorem to find the other two sides.
Answer: help
Step-by-step explanation:
A computer costs 927 plus VAT where VAT is 20%. We need to find the total cost of the computer.
The total cost = original cost + VAT
Total Cost = 927 + 20% * 927
20% converts to decimal by moving the decimal 2 units up, so it is 0.2
= 927 + 0.2*927
Multiply to find value of tax
= 927 + 185.4
Add to find the total cost
Total cost = 1112.4 euros
B, is the only solution where x=0 isn’t the answer because 2.5x+3=x and if u subtract the 2.5x you get 3= -1.5x and if you divide 3 by -1.5 it won’t be x=0
it is true because al triangles angles MUST add up to 180
