Answer: Shorter leg = 6 inches
Longer leg = 6+2 = 8 inches
Step-by-step explanation:
Let the shorter leg bw represented by x.
Therefore, the longer leg will be x+2.
The hypothenuse is 10inches
We should note that in Pythagoras theorem, the square of the longer and shorter side equals the square of the hypothenuse. This will be:
x² + (x+2)² = 10²
x² + x² + 4x + 4 = 100
2x² + 4x = 100 - 4
2x² + 4x = 96
2x² + 4x - 96 = 0
x² + 2x - 48 = 0
x² + 8x - 6x - 48 = 0
x(x + 8) -6(x + 8) = 0
x - 6 = 0
x = 0+6.
x = 6
Shorter leg = 6 inches
Longer leg = 6+2 = 8 inches
Answer:
x ≈ 48.2°
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos x = 
= 
, then
x = 
( ) ≈ 48.2° ( to the nearest tenth )
Answer:
y = -2x + 6
Step-by-step explanation:
y = mx + c
m = (2-4)/(2-1) = -2/1
m = -2
y = -2x + c
When x = 1, y = 4
4 = -2(1) + c
c = 4 + 2 = 6
y = -2x + 6
I think the answer would be 28. Hope this helps!
