Write an expression to represent the area of a right triangle with legs length as follow: 2x-2 and 4x+2

1 answer:

8 0

For Right angled triangle area
A=ab/2
(2x-2)(4x+2)/2
(8x^2+4x-8x-4)/2
(8x^2-4x-4)/2 take common term 2
2(4x^2-2x-2)/2
So A=4x^2-2x-2

∠A=56°

∠B=34°

∠C=180-(56+34)=180-90=90°

$\frac{20}{sin 90} =\frac{BC}{sin 56} \\BC=20 sin 56 \approx 16.58 miles$

Please help me with this problem.

Answer:

y = 10/2x + 0

Step-by-step explanation:

Slope Int Form: y = m(slope)x + b(y-intercept)

The number before the x is the slope. To find the slope, count how far up or down and how far to the right or left. The b in the equation is the y-int so find the y-int of the graph.
