Question

Two right triangles are congruent. Find the value of x.

Answer 1

I got 5.3 repeated.. I think it's wrong :/

Answer 2

ok so if they are congruent let's pretend they are the same triangles
sorry for the imperfect triangle.

Answer 3

Haha, it's fine. Looks GREAT (: okay.. drawing this down.

Answer 4

ok so you have all the things needed to solve this
you have two angles 33 and 90.
do you know the triangle sum conjecture?
well if you don't three angles in a triangle will add up to 180
so if you have two you can subtract that from 180 to get the final one
now i don't know why they gave you that equation 9x-15 but i will
solve it both ways to double check.
so lets try adding 33+90= 123
180-123 = 57
so the base angle should be 57
lets try it with the equation
9x - 15 +33 = 180
9x + 18 = 180
-18 -18
9x = 162
x = 18
now that is just the value of x
but the angle is 9x - 15 so lets plug in 18
9(18) - 15
162 - 15
147
yeah so 147 and 57 are not the same :(

Answer 5

Ok im guessing these triangles aren't congruent
what if we just solve each one?
