Question

please helppp me i am so bad at this

Answer 1

Answer:

• x = 4√6 or 9.8

Step-by-step explanation:

The two smaller triangles are similar.

The ratio of corresponding sides of similar triangles is equal:

• 12/x = x/8
• x² = 12*8
• x² = 96
• x = √96
• x = 4√6 or 9.8

Answer 2

• x is the angle bisector of a right angle . Applying Thales theorem

$\\ \sf\longmapsto x^2=12(8)$

$\\ \sf\longmapsto x^2=96$

$\\ \sf\longmapsto x=\sqrt{96}$

$\\ \sf\longmapsto x=9.7$
