Answer:
x = 55
Step-by-step explanation:
a triangle's angles must equal when added up to 180.
so
76 + 49 + x = 180
combine terms
125 + x = 180
x = 55
A= -81 + square root of 113

X=1 so it is 1×1×1=1 so.... it is 19+1
Answer: I wrote the answer in docs so here is the pic for the whole equation i explained it too! I hope this helped
HL Theorem would prove these two triangles are congruent.
