Answer:
ab = 144
Step-by-step explanation:
Assuming you mean a² + b² = 612, then
(a + b)² = a² + 2ab + b² , that is
30² = a² + 2ab + b² , so
a² + 2ab + b² = 900
a² + b² + 2ab = 900 ← substitute a² + b² = 612
612 + 2ab = 900 ( subtract 612 from both sides )
2ab = 288 ( divide both sides by 2 )
ab = 144
Here, sum of all the angles would be equal to 360.
We can see there are two right angles (=90)
So, 90 + 90 + x + 60 = 360
240 + x = 360
x = 360 - 240
x = 120
In short, Your Answer would be 120
Hope this helps!
Answer: Can u post a question?
Step-by-step explanation:
The linear equation is y = 4 + 0.5x
<h3>How to determine the equation?</h3>
The points are given as: (-2,3) and (4,6)
The equation is then calculated using:
Substitute the known values
Evaluate
y = 0.5 *(x+2) + 3
Expand
y = 0.5x + 1 + 3
Evaluate the sum
y = 0.5x + 4
Rewrite as:
y = 4 + 0.5x
Hence, the equation is y = 4 + 0.5x
