O is the centre of the circle, EF is a tangent, angle BCE=28 degrees, angle ACD=31 degrees.
Yuki888 [10]

Answer:

a. 28˚

b. 76˚

c. 104˚

d. 56˚

Step-by-step explanation

a. because angle between tangent and chord is equal to the angle(s) in alternate segment.

b. because angles in triangles add up to 180˚, 180-28=152 and because isosceles triangle, 152/2=76˚

c. because angles in triangles add up to 180˚ and opposite angles in a cyclic quadrilateral add up to 180˚, 31+76=107, 180-107=73, 73-28=45, angles in triangle so 180-(31+45)=104˚

d. 28*2=56˚ because angles at circumference are half angles at centre

List the sides of each triangle from shortest to greatest
Lelechka [254]
In every triangle, the largest side, is opposite the largest angle.

Also, the smallest side, is opposite the smallest angle.


a.70^o\ \textgreater \ 60^o\ \textgreater \ 50^o so |RQ|\ \textgreater \ |PR|\ \textgreater \ |PQ|, 

because RQ is opposite angle P, the largest,
PR is opposite angle Q , the middle
and PQ is opposite angle R, the smallest.

Greatest side: RQ


b. The sum of the measures of the interior angles of any triangle is 180°, 

so 

m(A)+m(B)+m(C)=180^o\\\\50^o+45^o+x=180^o\\\\x=180^o-50^o-45^o=85^o

thus, m(C) is the largest angle. This means the largest side is the side AB.



Answers:

a) RQ
b)AB
