Answer:
it should be 67/65 or if in mixed number form : 1 2/65
Answer:
The lenghts of both legs: 
Step-by-step explanation:
By definition, when a triangle has angles that measures 45°, 45° and 90°, its legs are congruent.
Then, knowing the lenght of the hypotenuse, we can find the lenght (in inches) of any leg of the given triangle by applying the Trigonometric Identity
:

Finally, simplifying, we get:

Ezpeezee:
Since we know the two angle measures equals 145...
(4x+5)+(6x-10)=145
Combine like terms and you get...
10x-5=145
Solve for x...
Add 5 on both sides and you get 150. Then divide by 10 and you get 15.
However, we arent finished yet... We still need to find XMN. The equation for m<XMN= 6x-10. PLUG 15 IN FOR X...
90-10
and that simplifies to 80 degrees.
Any questions?
Answer:
I believe that X=10 .
