Answer 1

Answer:

A

We will apply exterior angles property of Triangles

(Exterior angle is equal to the sum of other two angles)

angle YRQ = angle P + angle Q

= 60+70

=130 degree

B

We will apply angle sum property of triangles

(The sum of all interior angles of a triangle  is 180 degree)

Angle PRQ = 180-(angle P + angle Q)

=180-(60+70)

= 180-130

=50 degree

ANSWER

a)130 degree

b) 50 degree

Answer 2

Answer:

Here's the answer

Explanation:

a)

<YRQ = <RPQ + <PQR                              {SUM OF EXTERIOR ANGLE IS EQUAL

<YRQ =60+70                                                      TO EXTERIOR ANGLE}

    <YRQ =130 

b)

let <PRQ be x

then

<RPQ + <PQR + <PRQ = 180                      {ANGLE SUM PROPERTY}

60 + 70 + x = 180

130 + x = 180

x = 180 - 130

x = 50
