Answer:75g
Step-by-step explanation: It os small
√49 is a rational number.
Given this, we know:
A+B+90° = 180°
Therefore:
90°-A = B and 90°-B = A
We also know:
sin(A) = a/c
<span>cos(B) = a/c</span>
therefore,
Sin (A)=Cos (B)
A. angel a is 50 bc since it is isosceles, the two ungiven angles equal the same (180-80=100, 100/2=50)
B. 180=28+28+b, 180=56+b, 124=b
