<span>A) 2x + 4y = 38
B) 10x + 3y = 105
Multiplying A) by -5
A) -10x -20y = -190 then adding it to B)
</span><span>B) 10x + 3y = 105
-17y = -85
y = 5
x = 9
</span>
Answer:
The product of 4 times the quantity x to the fifth power

Answer:
D) 140°
Step-by-step explanation:
The total number of degrees in a triangle is 180. Since both sides of the triangle are the radius of the circle, the triangle is isosceles. Therefore the two opposite angles are equal. Thus, the central angle is 180° − 2(20°) = 140°.
It is ASAF
In both Triangles,
AB = AD (Given)
AC = AE (Given)
∠CAB = ∠EAD (Vertically opposite angles)
So,
By SAS rule of congruency,
∆ABC = ∆ADE
