What are similar triangles?If two triangles' corresponding angles are congruent and their corresponding sides are proportional, they are said to be similar triangles. In other words, similar triangles have the same shape but may or may not be the same size. The triangles are congruent if their corresponding sides are also of identical length.
Corresponding sides of similar triangles are in the same ratio. The ratio of area of similar triangles is the same as the ratio of the square of any pair of their corresponding sides
Given data ,
Let the first triangle be represented as ΔABC
Let the second triangle be represented as ΔEAD
Now , the measure of side AC = 4.8
The measure of side BA = 3.1
And , the measure of side EA = 4.8
The measure of side DA = 3.1
And , Corresponding sides of similar triangles are in the same ratio
So , the triangles ΔABC and ΔEAD are similar
Therefore , the angles will also be congruent
The measure of ∠ACB = The measure of ∠DEA = x°
The measure of ∠DEA = 180° - ( 53° + 86° ) ( angles of a triangle = 180° )
On simplifying the equation , we get
The measure of ∠DEA = 41°
Hence , the measure of x = 41° and they are similar triangles

Step-by-step explanation:
Conversion a mixed number 3 3/
4
to a improper fraction: 3 3/4 = 3 3/
4
= 3 · 4 + 3/
4
= 12 + 3/

To find new numerator:
a) Multiply the whole number 3 by the denominator 4. Whole number 3 equally 3 * 4/
4
= 12/

b) Add the answer from previous step 12 to the numerator 3. New numerator is 12 + 3 = 15
c) Write a previous answer (new numerator 15) over the denominator 4.
Three and three quarters is fifteen quarters
Conversion a mixed number 2 2/

Find the missing angle.
86°
84•
?
36
Answer:
? = 64°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
The third angle in the triangle on the right is
third = 180° - (84 + 36)° = 180° - 120° = 60°
Thus the third angle in the triangle on the left is
third = 90° - 60° = 30° , then
? = 180° - (86 + 30)° = 180° - 116° = 64°

3. Greg's family went to the movie theater and bought
tickets and popcorn. They spent $35 altogether with $9.50
spent on popcorn.
Write an equation that can be used to find out how much
money x they spent on tickets. (DO NOT use $ in your
equation, please.)
McGraw
Answer:
$25.50
Step-by-step explanation:
35 - 9.5 = x
25.5 = x
Answer:
Step-by-step explanation:
Let p=pop corn and x=tickets.
Because they have $9.50 on popcorn you should subtract 9.50 from 35. This gives you $25.50 dollars.
Because you know that they used the rest of the money to but tickets, they spent $25.50 on tickets
Therefore the equation should be 35-9.50=x or x=35-9.50

How many 3/8 's are in 6? Can someone answer this step by step :,)
Answer:
16
Step-by-step explanation:
Here we will show you how to calculate 6 divided by 3/8. We will give you the answer in fraction form and in decimal form.
Here is 6 divided by 3/8 displayed mathematically in colors:
6
÷
3
8
The numbers in 6 divided by 3/8 are labeled below:
6 = whole number
3 = numerator
8 = denominator
To make it a fraction form answer, you multiply the whole number by the denominator and make the result the new numerator. The old numerator becomes the new denominator:
6 x 8
3
=
48
3
Thus, the answer to 6 divided by 3/8 in fraction form is:
48
3
To make the answer to 6 divided by 3/8 in decimal form, you simply divide the numerator by the denominator from the fraction answer above:
48 / 3 = 16
The answer is rounded to the nearest two decimal points if necessary.
48/3 can be simplified to 16/1.
16/1 is an improper fraction and should be written as 16.
