Answer:
Angle 1 = 46°
Angle 2 = 44°
Step-by-step explanation:
Given:
Angle 1 = (4x - 2)°
Angle 2 = (3x + 8)°
Angle 3 = 90°
Find:
All acute angle
Computation:
Using angle sum property
Angle 1 + Angle 1 + Angle 1 = 180°
(4x - 2)° + (3x + 8)° + 90° = 180°
7x + 6 = 90
7x = 84
x = 12°
So,
Angle 1 = (4x - 2)° = 4(12) - 2 = 46°
Angle 2 = (3x + 8)° = 3(12) + 8 = 44°
Answer:
y=-5x+17
Step-by-step explanation:
Answer:
(a) 100° , (b) 235°
Step-by-step explanation:
the bearing is the angle measured in a clockwise direction from the north line.
(a)
the bearing of D from C is the angle NCD
∠ NCD = 100°
then the bearing of D from C is 100°
(b)
the bearing is the angle from the north line at C , measured clockwise to D
that is the green shaded ∠ NCD = 235°
the bearing of D from C is 235°
