Answer:
The radius of circle is 4
Step-by-step explanation:
Given as :
The equation of circle is given as :
x² + y² = 16
Now The standard equation of
( x - h )² + ( y - k )² = r²
where h , k are center of circle
r is the radius of circle
From given circle equation x² + y² = 16 can be written as
( x - 0 )² + ( y - 0 )² = (4)²
So, The center of this circle is ( h , k ) = ( 0 , 0 ) And radius of circle = 4
Hence The radius of circle is 4 Answer
Answer:
Therefore
m Angle 1 = m Angle 2 = 31° ...Justified
Step-by-step explanation:
Given:
m angle 1 = ( 3x + 10 )°
m angle 2 = ( 5x - 4 )°
To Find:
m∠1 = ?
m∠2 = ?
Solution:
Vertical Angles:
The angles opposite each other when two lines cross. They are always equal.
∴ m Angle 1 = m Angle 2
Substituting the given values we get

Substituting ' x ' in Angle 1 and Angle 2 we get
m Angle 1 = 3 × 7 + 10 = 31°
m Angle 2 = 5 × 7 - 4 = 31°
Therefore
m Angle 1 = m Angle 2 = 31° ...Justified
Answer:
find the square root of 64
x=8
Step-by-step explanation:
Ratio 1:5....added = 6
complimentary angles, when added, = 90 degrees
1/6(90) = 90/6 = 15
5/6(90) = 450/6 = 75
so ur 2 angles are : 15 and 75
