apply Pythagorean theorem
c= longest side (hypotenuse)
so 25=a^2 + b^2?
yes a= ?? b= ??
is there one x we need to find or 2?
i think just x …cuz the sides are equal
c= 5 a=x and b= x 45-45-90 triangle has two equal sides
strange.. usually we have 2 sides and 1 unknown? or has it been too long since I've seen a problem like this?
ya… i was thinking maybe of using sohcantoa somehow??
can you post a screenshot of this problem?
i can’t on an iPad..i tried.. but i drew exactly what they gave me
would it be 5* sin(45)?
what's the subject you working on ?
have you learned sin cos
ya kind of
i did sin45=opposite/5 then 5* sin45…
|dw:1439558158478:dw| both sides are same i guess you have to use sin
yes then solve for x
ya cuz 3.5^2 +3.5^2=24.5
so then x=3.5 ?
yeah you can round it to 25
so \[(3.5)^2+(3.5)^2 =5^2\]
