Answer:
value of a = 79
Step-by-step explanation:
by solving it we get,
=》a - 32 = 47
=》a = 47 + 32
=》a = 79
hence, a = 79
They are similar triangles so 20/4=15/x
solve for x
20x=15*4=60
x=3
Answer:
<em>Gradient of KL = 2</em>
Step-by-step explanation:
From the diagram, we are to calculate the gradient of KL. Gradient is salso known as the slope of the line.
Gradient of KL = ΔOK/ΔOL
Given
OK = 2OL
Substitute into the formula
From the diagram, ΔOL = -5
ΔOK = 2ΔOL
ΔOK = 2(-5)
ΔOK = -10
Hence;
Gradient = -10/-5
<em>Gradient of KL = 2</em>
