Answer:
Step-by-step explanation:
First you need to find the are between everything
So SA= 1/2 length time width.
I am also pretty sure then you find the circumference and diameter of a circle.
The answer is 153 degrees
Answer:
the slope is -1/4
Step-by-step explanation:
the change in y over the change in x from point (-2,-2) to (2,-3) is how to find the slope
y1-y2/x1-x2 = m
-2--3/-2-2 = -1/4
Answer:
36
Step-by-step explanation:
45*(9/5)=81(The whole score)
81-45=36(the second half score)
Answer:
Area of triangle = 20√2
Step-by-step explanation:
Formula:
Area of triangle = bh/2
b - base of triangle
h - height of triangle
<u>Distance formula</u>
d = √(x₂ - x₁)² +(y₂ - y₁)²
From the figure we can see that, the given triangle is right angled triangle.
Base = AC and Height = AB
<u>To find AB and AC</u>
A(1,3), B(4,7) and C(9, -5)
AB = √(4 - 1)² +(7 - 3)² = √(3² + 4²) = 5
AC = √(9 - 1)² +(-5 - 3)² = √(8² + -8²) = 8√2
<u>To find the are of triangle</u>
Area = bh/2 = (5* 8√2)/2 = 20√2
Therefore the area of triangle = 20√2 square units
