Answer:

  • 39° 44' 52''

Step-by-step explanation:

<h3>Given</h3>
  • m∠DXB = 70° 15' 12''
  • m∠DXC = 30° 30' 20''
<h3>To find</h3>
  • m∠CXB
<h3>Solution</h3>

<u>According to Angle Addition postulate:</u>

  • m∠DXB = m∠DXC + m∠CXB

<u>Therefore</u>

Determine the length of the legs in the right triangle below.
Marysya12 [62]

Answer:

x = 14

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

x² + x² = (14\sqrt{2} )²

2x² = 392 ( divide both sides by 2 )

x² = 196 ( take the square root of both sides )

x = \sqrt{196} = 14

Thus the congruent legs are 14 cm
