Answer:

Based on the Z angle rule

g) X=33

Total angle in a triangle=180 degree, therefore 33+71=104.. so 180-104=76(y)

Y=76

h) X=80

Y=280

Using the same Z angle rule, 41+39=80 degree which is the value of X. Now a total reflexive angle measure 360, therefore 360-80=280 degree which is the value of Y

What is the simplified form of x+6 over x+4 + x-3 over 3

Zigmanuir [339]

1 Cancel 33
x+\frac{6}{x}+4+x-1x+x6+4+x−1
2 Collect like terms
(x+x)+\frac{6}{x}+(4-1)(x+x)+x6+(4−1)
3 Simplify
2x+\frac{6}{x}+32x+x6+3

1. A chord is 22 cm long. It is 60 cm from the center of the circle.

mezya [45]

Answer:

Radius, r = 61 cm

Step-by-step explanation:

According to the attached figure, we have,

Length of chord, AB = 22 cm

Such that, AP = PB = 11 cm

OP = 60 cm

It is required to find the radius of the circle. We know that radius of a circle is perpendicular to chord. So, APO forms a right angled triangle. Using Pythagoras theorem to find the radius of circle. Let it is r. So,

$r^2=60^2+11^2\\\\r=61\ cm$

So, the radius of the circle is 61 cm.
