Answer:
∠ HCF = 108°
Step-by-step explanation:
∠ ABG and ∠ HCF are alternate exterior angles and are congruent, thus
12x = 11x + 9 ( subtract 11x from both sides )
x = 9
Thus
∠ HCF = 11x + 9 = 11(9) + 9 = 99 + 9 = 108°
Answer:
387
Step-by-step explanation:
1. 16*4= 64
2. 64*6=384
3. 384+3=387
Step-by-step explanation:
1. In the picture down below.
2. Because they are = 20
100 ÷ 5 = 20
10 ÷ 0.5 = 10 x 2 = 20
1 ÷ 0.05 = 1 x 20 = 20
( 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°
