Answer:

length of the legs is

Step-by-step explanation:

the both sides of the length of the legs of a right triangle are equal

So it form a isosceles triangle 45- 45- 90 degree triangle

the ratio of 45-45-90 degree triangle is

xsqrt(2) is the side opposite to 90 degree

so

Divide both sides by square root (2)

multiply square root (2) at the top and bottom

24.35°C is the answer

BCA = 45° BCD = 125° ACD = 180- (45+125) ACD = 180 - 170 ACD = 10°

I=PRT/100

Multiply both sides by 100

100I=PRT

divide both sides by the coefficient of P which is RT

PRT/RT= 100I/RT

P= 100I/RT
