( a )pairs of vertical angles :

AGB and EGD

Vertical angles are a pair of opposite angles formed by intersecting lines. Vertical angles are equal in magnitude.

( b ) a pair of adjacent angles :

AGB and BGC

Adjacent angles are two angles that have a common side and a common vertex (corner point) but do not overlap in any way.

(c) Name a pair if supplementary angles :

AGB and BGD

Two angles are called supplementary when their measures add up to 180 degrees.

(d) A pair of complementary angles :

AGF and FGE

Two angles are called complementary when their measures add to 90 degrees.

(e) Find measure of CGD :

( look into the photo attached for better understanding)

CGD = 55°

How to factor ax2 bx c?
Burka [1]

In the same way as you could factor trinomials on the form of

<span><span><span>x2</span>+bx+c</span><span><span>x2</span>+bx+c</span></span>

You can factor polynomials on the form of

<span><span>a<span>x2</span>+bx+c</span><span>a<span>x2</span>+bx+c</span></span>

If a is positive then you just proceed in the same way as you did previously except now

<span><span>a<span>x2</span>+bx+c=<span>(<span>x+m</span>)</span><span>(<span>ax+n</span>)</span></span><span>a<span>x2</span>+bx+c=<span>(<span>x+m</span>)</span><span>(<span>ax+n</span>)</span></span></span>

<span><span>where  c=mn,ac=pq         </span><span>and b=p+q=am+<span>n</span></span></span>

Ilya [14]
You need to use the angle sum of  a triangle in triangle CAD to express y in term of x
for triangla CAD , y = (180 -x) /2
180 = 3x + [ (180-x)/2]

x = 36
