Answer:
Option 3
Step-by-step explanation:
The two triangles are proved congruent to each other so CPCTC proves that the angles are also congruent.

Answer:
15x+98=105
-98 -98
15x=7
/15 /15
x=7/15
Step-by-step explanation:
x=7/15
Remark
You are in the 4th quadrant. The only way I know how to do this is to use the double angle formula.
Formula
Sin(a + b) = sin(a) * cos(b) + sin(b)*cos(a)
Givens
a = - 45
b = - 30
Substitute
Sin(-45 - 30) = sin(-45) * cos(-30) + sin(-30)*cos(-45)
Sin(-75) = -sqrt(2)/2*sqrt(3)/2 - 1/2 * sqrt(2)/2
Sin(-75) = -sqrt(6) / 4 - sqrt(2)/4
Sin(-75) =

Answer:
Large Angle = 63
Step-by-step explanation:
Complementary Angle = 90 °
x + x + 36 = 90
2x = 54
x = 27
Large Angle : 27 + 36 = 63
Smaller number =27
