In a triangle, the measure of angle C is (x+30*). the measure of angle A is_________?

*= degrees


A Angle B is of course 90*


[\ Angle C is (x + 30*)


[ \


[ \


[____\


B C








the image i made is not drawn to scale...


i dont understand this multiple choice question


please show how u found the answer








a) (60 - x)*


b) (90 - x)*


c) (120 - x)*


d) (x - 60)*


e) (x - 120)*





thankyou

ok so we know B = 90 (based on your drawing)


and A+B+C=180


A+90+x+30=180


A=180-x-120


A=60-x
Reply:The sum of the angles in any triangle = 180º





B = 90º


C = (x + 30)º = xº + 30º





A + B + C = 180





A + 90 + x + 30 = 180


subtract (90 + x + 30) from both sides to isolate A





A = 180º - 90º - xº - 30º





A = 60º- xº = (60 - x)º
Reply:the data is not completely
Reply:you cant tell tht but if you know one of the tht then you can find the value of x but i can tell you this tht its not a, b, or c


b/c in this case you 've to add the two expression and make it equalt to 90 degrees b/c tht the sum of two acute angle in right triangle








but you cant 've c or d either b/c the value exceeds the limit of 90





so it can only b a, in which case x will cancle out wehn you add it but atleast you end up with 90=90





so x could be any real number, and anser is a
