The answer is A. the first step in making a copy of an angle is to draw a ray away from the original angle.
I know that's what it says here, but you can draw the ray in the same direction just have the ray on a different spot on the paper than the original angle.
a:
The side-side-side (SSS) theorem. It states that, if two triangles have the same side lengths, they are congruent.
b:
You should have three ovals saying:
- AB=A'B' (given)
- AC=A'C' (given)
- BC=B'C' (given)
These three ovals will point to the final oval, containing ABC=A'B'C', justified with "SSS"
c:
In this case, congruence implies similarity, so you don't have to change anything. In general, it is sufficient to prove that the three angles have the same measure to prove similarity, and this is not enough to prove congruence.
It is important to keep a
close eye on all the information’s that are given in the question. Based on
those given information’s the answer can be easily deduced.
The distance traveled by Linda in 3 hours = 4.8 miles
Then
In 1 hour the distance traveled by Linda = (4.8/3) * 1 miles
= 1.6 miles
So the speed of Linda is 1.6 miles per hour.
I hope the procedure is simple
enough for you to understand. You can always solve similar kind of problems
using this simple procedure.
The question is incomplete. Here is the complete question.
Semicircles and quarter circles are types of arc lengths. Recall that an arc is simply part of a circle. we learned about the degree measure of an ac, but they also have physical lengths.
a) Determine the arc length to the nearest tenth of an inch.
b) Explain why the following proportion would solve for the length of AC below:
c) Solve the proportion in (b) to find the length of AC to the nearest tenth of an inch.
Note: The image in the attachment shows the arc to solve this question.
Answer: a) 9.4 in
c) x = 13.6 in
Step-by-step explanation:
a) , where:
r is the radius of the circumference
mAB is the angle of the arc
arc length =
arc length =
arc length = 9.4
The arc lenght for the image is 9.4 inches.
b) An <u>arc</u> <u>length</u> is a fraction of the circumference of a circle. To determine the arc length, the ratio of the length of an arc to the circumference is equal to the ratio of the measure of the arc to 360°. So, suppose the arc length is x, for the arc in (b):
c) Resolving (b):
x =
x = 13.6
The arc length for the image is 13.6 inches.
