When going down on a Cartesian coordinate system, you are moving in the negative direction, so-7
If you are trying to figure out x-9=15 it’ll be 24
Answer:
d. 15, 30, 135
Step-by-step explanation:
A triangle's interior angles on a flat surface add up to 180 degrees.
a. 90 * 3 = 270 != 180
b.(80 * 2) + 200 = 360 != 180
c.40 + 50 + 60 = 160 != 180
d.15 + 30 + 135 = 45 + 135 = 180, so it has to be d.
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

Answer:
≈ 153.86
Step-by-step explanation:
Area of a circle's formula is: A = πr² π in this would be approximately 3.14
using this formula and the given radius, we can plug it into the formula
A = (3.14)(7)² --> A= (3.14)(49) ≈ 153.86
