Answer:
B
Step-by-step explanation:
a^2 + b^2 = C^2
solve for b
b^2 = c^2 - a^2
square root on both sides of the equation and you get option b as your answer
Answer:
13 units
Step-by-step explanation:
The legs of an isosceles trapezoid are congruent, then
x + 8 = 48 - 7x ( add 7x to both sides )
8x + 8 = 48 ( subtract 8 from both sides )
8x = 40 ( divide both sides by 8 )
x = 5
Then
leg = x + 8 = 5 + 8 = 13
Answer:
Step-by-step explanation:
1. x = y-4
0 = y - 4 -x
4 = y - x
2. 2x+4y = 10
x+4y = 5
x+y = 5/4
Answer:
x = 14 cm
Step-by-step explanation:
200 000 cm = 2 km
1 cm ............... 2km
x cm ..............28 km
x = 28*1/2 = 28/2 = 14 cm
