Tatiana [17]3 years ago

Answer:

Step-by-step explanation:

an isosceles triangle, 2 angles equal to 45, one is 90 degrees

in this case a=b

c^2=a^2+b^2, lets solve for a, as it doesn't matter which leg we find first due to the fact that they are equal

c^2=2a^2

10^2=2*a^2

100/2=a^2

50=a^2

a=5\sqrt{2}

Which of the following has no solution?
Softa [21]

Answer:

(x + 1 s 1) n (x + 12 1)

(x +1<1) n (x + 1 > 1)

Step-by-step explanation:

Just simplify each the statements.

Then compare and and see if the statements are contradictory and therefore FALSE, if so, then there is no solution.

(x + 1<-1) n (x + 1< 1)

(x <-2) n (x < 0) which is true, so there is a solution.

(x + 1 s 1) n (x + 12 1)

this doesn't make sense so there is no solution.

(x +1<1) n (x + 1 > 1)

(x < 0) n (x > 0)

This is not possible, the statements are contradictory and therefore FALSE, so there is no solution.
