Answer:
y=-2/3x+20/3
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(4-6)/(4-1)
m=-2/3
y-y1=m(x-x1)
y-6=-2/3(x-1)
y=-2/3x+2/3+6
y=-2/3x+2/3+18/3
y=-2/3x+20/3
The value of x in each figure is 34°, 17.1° and 75° respectively.
<h3>What is an
equation?</h3>
An equation is an expression used to show the relationship between two or more numbers and variables.
From the diagram:
1) x + 146° = 180° (sum of angles in a straight line)
x = 34°
2) x + 62.9° = 90° (complementary angles)
x = 17.1°
3) x + 105° = 180° (sum of angles in a straight line)
x = 75°
The value of x in each figure is 34°, 17.1° and 75° respectively.

Answer:
12.4967 m
≈ 12.5 m
Step-by-step explanation:
From the solution diagram attached, to find /AB/, we apply sine rule:
AB/Sin 140° =AD/Sin 15°
AB = 10/Sin 15° x Sin 140°
= 24.8372 m
To calculate the height of the pole we will calculate BC first. Using the right angle triangle ∠ABC, we have:
Sin ∅ = BC/AB
Sin 25° = BC/ 24.8372
BC = 24.8372 Sin 25°
= 10.4967 m
The height of the pole = BC + 2.0
= 10.4967 + 2.0
= 12.4967
≈ 12.5 m
