Answer:

75

Step-by-step explanation:

Adjacent angles add to 180

x + 2x-45 = 180

Combine like terms

3x - 45 = 180

Add 45 to each side

3x = 180+45

3x =225

Divide by 3

3x/3 = 225/3

x =75

What is the length of the unknown leg in the right triangle 3 ft
pishuonlain [190]

<u><em>Answer:</em></u>

a = 3 ft

<u><em>Explanation:</em></u>

The relation between the legs and the hypotenuse of a right-angled triangle can be expressed using the Pythagorean theorem as follows:

(hypotenuse)^2 = (leg1)^2 + (leg2)^2

<u>In the given triangle, we have:</u>

leg1 = 8 ft and hypotenuse = \sqrt{73} ft

<u>Substitute with the givens in the above equation to get the length of the second leg as follows:</u>

(\sqrt{73})² = (8)² + (second leg)²

73 = 64 + (second leg)²

(second leg)² = 9

either second leg = +\sqrt{9} = 3 ft ............> accepted

or second leg = -\sqrt{9} = -3 ft ................> rejected as length cannot be negative

Hope this helps :)
