Answer:
x=90° and y= 43°
Step-by-step explanation:In ∆ABC Applying
Angle sum property
47°+47°+2y=180°
y=43°
In ∆ABD Applying Angle sum property
x=90°
Answer:
Below in bold
Step.-by-step explanation:
It consists of 5 isosceles triangles of equal sides 4 cm and vertex angles 360 / 5
= 72 degrees.
Area of 1 triangle = 1/2 * 4^2 *sin 72
Area of the whole pentagon = 5 * 1/2 *4^2 * sin 72
= 38.04 cm^2.
The interval notation given to us means that x is between negative infinity and 5, excluding both endpoints.
So we can write
which shortens to 
The graph will have an open hole at 5 on the number line, and shading to the left to indicate all points smaller than 5.
