Answer:
Step-by-step explanation:
a). Since, ΔABC ~ ΔWYZ
Their corresponding sides will be proportional.
--------(1)
By applying Pythagoras theorem in ΔABC,
AB² = AC² + BC²
BC² = AB² - AC²
BC² = (194)² - (130)²
BC² = 20736
BC = 144
From equation (1)
WY =
WY = = 1.35
WZ =
WZ = = 0.90
b). tan(A) =
=
=
Since, ΔABC ~ ΔWYZ,
∠A ≅ ∠W
Therefore, tangent of angle A and angle W will measure .
The linear inequality of the graph is: -x + 2y + 1 > 0
<h3>How to determine the linear inequality?</h3>First, we calculate the slope of the dashed line using:
Two points on the graph are:
(1, 0) and (3, 1)
The slope (m) is:
This gives
m = 0.5
The equation of the line is calculated as:
So, we have;
This gives
Multiply through by 2
Now, we convert the equation to an inequality.
The line on the graph is a dashed line. This means that the inequality is either > or <.
Also, the upper region of the graph that is shaded means that the inequality is >.
So, the equation becomes
2y > x - 1
Rewrite as:
-x + 2y + 1 > 0
So, the linear inequality is: -x + 2y + 1 > 0
