So, first you must find the remaining angle measure. To do this add 25 and 90 then subtract from 180. The remaining angle measure is 65 degrees.
Next, use tangent, cosine, or sine to find the remaining side lengths.
I used sine of 25 which is opposite of hypo. which is sine 25 = y/43.
Multiply both side by 43 and you get y=18.17
Do the same to find x, but use the sine of 65, and you get sine 65 = x/43.
Multiply both sides by 43 and you get x=38.97
Hope this helped!
the larger triangle has angles of 75° and 55°.
the smaller triangle has angles of 75° and 55°.
the triangles are similar by AA.

Step-by-step explanation:
Well lets go through what I know
- The answer to the first one (A) is 49 and were looking for 45
- Second questions answer (B) is 45 and that's the number were looking for so there's no need to go any further.
So the answer we are looking for is (B) 45
Hope this helps!
