I need some major help with this proof.

The first one is always what is given.
Then work through the rest.
See the attached picture:
Answer:
This one is actually in order already.
First box to A.
Second box to B
Third box to C.
Fourth box to D.
Fifth box to E.
Step-by-step explanation:
You always start with the given. So the first box goes to A.
The second box goes with B. When angle is bisected it is cut into two congruent halves. That means that left part of the angle of A has an equal measurement to that of the right part of the angle of A. So Angle BAD is congruent to Angle CAD.
Those base angles are B and C even though it isn't written there.
x (related) x is the reflexive property. This is what you have here where the related part is the congruence and the element being talking about is AD on both sides. So The third box goes with the reflexive option. The third box goes with C.
So you have by the given that AB and AC are congruent; those are the left and right leg of the big triangle.
You also have that Angle's BAD and CAD are congruent (those are the angles at the top in the two different triangles. You also have that they share the side right after.
So you are given 2 corresponding sides are congruent and the angle right between them in each is congruent.
We have enough information to prove the triangles are congruent by SAS. This fourth box should be matched with D.
Lastly, since the triangles are already congruent by SAS, then the other remaining corresponding sides are congruent and the other remaining corresponding angles are congruent. So Angle B and Angle C are congruent due to corresponding parts of congruent triangles are congruent. Last box is to be matched with E.

The length, to 1 decimal place, of the arc that subtends an angle of 5.4 radians at the center of a circle with a radius of 7 cm is 37.8 cm.
What is a circle?
It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)
It is given that:
The arc subtends an angle of 5.4 radians at the center of a circle with a radius of 7 cm.
As we know, the relationship between radius of the circle, central angle, and arc length is:
s = rθ
r = 7 cm
θ = 5.4 radians.
When two lines or rays converge at the same point, the measurement between them is called an "Angle."
s = 7×5.4
s = 37.8 cm
Thus, the length, to 1 decimal place, of the arc that subtends an angle of 5.4 radians at the center of a circle with a radius of 7 cm is 37.8 cm.

all very excited, as angles had been invented only a few years earlier:
In a 30-60 right triangle ...
the side opposite the 30 is half the hypotenuse
the side opposite the 60 is half the hypotenuse times the square root of three.
So the tangent of the 30 would be (opposite) / (adjacent) = (1/2h) / (1/2h√3) .
That's (1)/(√3) or (√3)/(3) .
