we know that
If two angles are congruent, that means, that the angles are equal
so
the measure of an angle congruent to a 47° is 47°
Answer:
Circumference of Circle A is about 16 units larger than the Circumference of Circle B
Step-by-step explanation:
Formula for Circumference of a circle = πd
Where, d = diameter of circle
Thus:
Circle A diameter = 13
Circle B diameter = 8
Therefore:
Circumference of Circle A = π*13 = 40.8407045 ≈ 41 unit (nearest whole number)
Circumference of Circle B = π*8 = 25.1327412 ≈ 25 unit (nearest whole number)
✔️Difference between circumference of Circle A and Circle B = 41 - 25 = 16
Therefore the Circumference of Circle A is about 16 units larger than the Circumference of Circle B
Answer:
The discriminant is equal to zero
Step-by-step explanation:
If x=6 is the only x-intercept of the graph of a quadratic equation, the it means the quadratic equation has a repeated root.
When a quadratic equation has a repeated root, it means its discriminant is zero.
This means that
Answer:
ABD= 58
BDC= 32
Step-by-step explanation:
complementary = 2 angles equal 90 degrees.
8y+2=90
Subtract 2 both sides.
8y=88
y=11
That's not all, put y into the equations.
ABD
5(11)+3
Multiply
55+3=58
BDC
3(11)-1
MULTIPLY
33-1
SUBTRACT
32
55.5 (the outside angle is going to be half of the inside angle if it’s on the center point)
