Given:
To find:
The 
.
Solution:
In circle B, 
is central angle and 
is inscribed angle from two points A and C.
According to central angle theorem, central angle is always twice of inscribed angle.
[Central angle theorem]
Divide both sides by 2.
Therefore, 
.
Answer:
y=65
x=50
Step-by-step explanation:
exterior angle of a triamgle is equal to sum of two interior angles
so
2y=130(as it is isosceles triangle)
y=65
we know y+y+x=180(sum of all angles of triangle)and (vertically opposite angle)
therefore, x=50
<u><em>Answer:</em></u>
The reduced form of
300
/28 is 75
/7
<u><em>Steps to simplifying fractions:
</em></u>
Find the GCD (or HCF) of numerator and denominator
GCD of 300 and 28 is 4
Divide both the numerator and denominator by the GCD
300 ÷ 4
28 ÷ 4
<em><u>Reduced fraction: </u></em>
75
/7
Answer:
180 mm
Step-by-step explanation:
height : cases
105 : 7
constant of proportionality = 105/7
height of 12 cases = 12 x 105/7 = 180 mm
