Answer:
C
Step-by-step explanation:
Since the triangle is right with hypotenuse h
Use Pythagoras' identity to solve for h
The square on the hypotenuse is equal to the sum of the squares on the other two sides, that is
h² = ( 5 )² + ( 5 )²
= 50 + 5 0 = 100
Take the square root of both sides
h = = 10 → C
b = 55°
c = 35°
b° = 180° - (85°+40°) = 180° - 125° = 55°
c° = 180° - (b°+90°) = 180° - (55°+90°) = 180° - 145° = 35°
I think its B.
so the lowest term is 1/10
