We can see that b and 140 are on a straight line. A straight line is an angle of 180. SO:
140 + b = 180
b = 40
As indicated by the arrows, the two horizontal lines are parallel, and also due to the transversal, we know that a and b are corresponding angles.
Therefore, a = 40, since corresponding angles are equal
b = 40
a = 40

Answer:
Give four examples of landforms where both the water and the land around it are flat.
Step-by-step explanation:
we conclude that the height of the triangle measures 12 centimeters.
<h3>
How to find the height of the triangle?</h3>
We know that the area of a triangle is given by the formula:
A = b*h/2
We can solve that equation for h, so we get:
h = 2*A/b
Now, we know that the area is 90cm^2, and the base measures 15 cm, replacing these two values we can get:
h = 2*(90cm^2)/15cm = 12cm
In this way, we conclude that the height of the triangle measures 12 centimeters.
