The longer leg of a right triangle is 6cm longer than the shorter leg and also 1cm longer than the hyptenese. find the perimeter
CaHeK987 [17]
X - a leg  (x > 6);
x - 6 - a leg;
x + 1 - a <span>hypotenuse;</span>
Use the Pythagorean theorem
(x+1)^2=x^2+(x-6)^2

Use:(a\pm b)^2=a^2\pm2ab+b^2

x^2+2x+1=x^2+x^2-12x+36\ \ \ |-x^2-2x-1\\\\x^2-14x+35=0\ \ \ |-35\\\\x^2-14x=-35\\\\x^2-2\cdot x\cdot7=-35\ \ \ |+7^2\\\\x^2-2\cdot x\cdot7+7^2=-35+7^2\\\\(x-7)^2=14\iff x-7=\pm\sqrt{14}\ \ \ |+7\\\\x=7-\sqrt{14} < 6;\ x=7+\sqrt{14}

x=7+\sqrt{14}\\x-6=1+\sqrt{14}\\x+1=8+\sqrt{14}

The perimeter:

7+\sqrt{14}+1+\sqrt{14}+8+\sqrt{14}=16+3\sqrt{14}

Answer:

see below

Step-by-step explanation:

1.  < 4 is the exterior angle of a triangle   given

2.  <1 + <2 + <3 =180   basic property of triangles

3.  <3 + <4 are a linear pair    <3 and <4 are adjacent and form a straight line

4. <3 and <4 are supplementary angles  supplementary angles are linear pairs

5.  <3 + <4 = 180   The definition of supplementary angles are that they add to 180 degrees

6.  <1 + <2 + <3 = <3+ <4  Substitute <3 + <4  for 180 in equation from step 2

7 <1 + <2 = <4   Subtract <3 from each side using the subtraction property of equality
