Type the correct answer in the box. use numerals instead of words. if necessary, use / for the fraction bar.

Angle B: 135 degrees

Angle A: 60 degrees

Angle C:  75 degrees

Step-by-step explanation:

Angle B is 135 degrees

We have the complement of angle B, which is the lowest left corner of the triangle and it says 45 degrees.

So, B = 180 - 45 = 135 degrees

Angle A.

The lines crossing form 2 pair of identical angles from their tip... The exterior angle is 60 degrees, so the interior angle A is also 60 degrees.

Angle C.

Just like for angle B, we get angle C by subtracting its complement:

C = 180 - 105 = 75 degrees.

We can also validate by calculating the sum of the interior angles of the triangle: 45 + 60 + 75 = 180, which is perfect.

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
