Answer:
90
Step-by-step explanation:
180°-104°=76°( sum of angles A and B)
76°÷2=38°
x=38°
Bcuz it is an isosceles triangle ( a triangle with 2 equal sides). So, angle B and A are equal. thats why 76° must be divided by 2.
180°-104°=76°(angles on a straight line)
180°-76°=104° (sum of angle A and C)
104°÷2=52°
y=52°
it is also an isosceles triangle.
x+y=38+52=90°
Answer:
5^ -8 or 1/ 5^8
Step-by-step explanation:
(5^-2)^4
We know that a^b^c = a^(b*c)
(5^-2)^4 = 5^(-2*4) = 5^(-8)
We know that a^ - b = 1/ a^b
5^ -8 = 1/ 5^8
Answer:
43
Step-by-step explanation:
Answer: x=-6
1. simplify both sides of equation
2. divide both sides by -2
Alright
This equation models a circle with a center of (-2 , 3) and a radius of 9
To check the point (6,3) how far is it from the center (-2,3):
using the distance formula:

therefore, this point lies INSIDE the circle, not on it nor outside it.
It is an
interior point.
