Answer:
Part a) The measure of the missing angle is 
Part b) The triangle of the figure is a right triangle
Part c) The triangle of the figure is a scalene triangle
Step-by-step explanation:
we know that
The sum of the interior angles of a triangle is equal to 
so
Let
x------> the missing angle
we know that
solve for x
The triangle of the figure is a right triangle --------> by its angles
Because the triangle has an angle measure of
The triangle of the figure is a scalene triangle --------> by its sides
Because the three angles and the three sides measures are different
Lateral area is the total surface area. A cube has 6 faces.
Lateral area = 6x²
<span>6x² = 144
</span>
<span>x² = 144/6
</span>
<span>x² = 24
</span>
<span>x² = </span>√24
x ≈ 4.899 km
Answer: subtraction property
x-(-6)=18
x+6=18
Subtract 6 from both sides
And you get x=12
Find the area of both shapes in the composite figure and add them together.
A of rectangle is 6 x 12
= 72
A of triangle is 1/2 x 8 x 5
=20
Add them together to get 92 inches^2
Hope this helps!!
Answer:
The telephone pole is 24 ft.
Step-by-step explanation:
30^2-18^2=b^2
900-324=b^2
576=b^2
\sqrt{576} =\sqrt{b^2}
24=b
b=height of telephone pole
