Answer:
a) 115°
b) 140°
c) 75°
d) 255°
Step-by-step explanation:
a) another line parallel to AB through E will split x into two sectors.
Parallel lines intersected by a third line makes opposite internal angles of equal value. Supplemental angles add to 180°
x = (180 - 120) + (180 - 125) = 115°
b) double application of parallel lines intersected by a third line making corresponding angles identical.
c) more of the same
d) more of the same
Answer:
THEY ARE 37 AND 28
Step-by-step explanation:
LET THE NUMBERS BE X AND Y
X = 9 + Y
X - Y = 9 ........1
X + Y = 65 .....2
ADDING 1 AND 2
2X = 74
DIVIDING BY 2
2X/2 = 74/2
X = 37
AND X = 9 + Y
: Y = X - 9
PUTTING X = 37
Y = 37 - 9
Y = 28
C = pi * d
a = pi * (d/2)^2
