Answer:
m∠E = 60°
Step-by-step explanation:
The given information in the diagram are;
The shape of the drawing, ΔEDF = A right triangle
The length of the hypotenuse side opposite the right angle = 16·√46
The length of the leg adjacent to the reference angle ∠E = 8·√46
By trigonometric ratio, we have;
Plugging in the values gives;
∴ m∠E = arccos(1/2)
Using a calculator or from tables or an online trigonometric ratio tool, we have
arccos(1/2) = 60°
∴ m∠E = arccos(1/2) = 60°.
The picture in the attached figure
we know that
In any quadrilateral where the vertices are on the circumference of a circle, the opposite angles add up to 180 degrees.
So,
in this problem
angle x + angle z = 180
the answer isx+z=180
Answer:
5
Step-by-step explanation:
(2x + y) - z
Let x=3 y=4 and z=5
2*3 +4 -5
Multiply and divide first
6 +4 -5
Then add and subtract
10-5
5
Answer:
3q+21
Step-by-step explanation:
I believe the expression would be:
x+2
For example, if you have the odd number 3 as x, 3+2 would be 5, the next odd number.
Hope this helped!! xx
