Can you please help me with this two questions ​

Mathematics
1 answer:
Natali [406]1 year ago
3 0

Answer:

2) d. 60°

3) a. AB

Step-by-step explanation:

<u>Question 2</u>

ΔABC and ΔCDA are <u>congruent</u> because:

  • they are both <u>right triangles</u>
  • they <u>share one side</u> (AC)
  • their hypotenuse are <u>parallel</u> (marked by the arrows)

This means the corresponding side lengths and angles are equal.

Therefore,

∠CDA = ∠ABC

⇒ x = 60°

<u>Question 3</u>

The <u>hypotenuse</u> is the <u>longest side</u> of a <u>right triangle</u> - the side opposite the right angle (the right angle is shown as a small square).

Therefore, the hypotenuse of ΔABC is the line AB.
