What is the measure of the remaining angle?
Enter the correct answer in the box.
Answers
Answer:
30+45+x=180(sum of all angles of triangle is equal to 180 degree)
75+x=180
x=180-75
x=105
The measure of the third interior angle is 105°.
What is a triangle?A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.
We also know that the sum of all the interior angles of a triangle is 180°.
Given, Two angles of a triangle have measures of 30° and 45°, assuming the third angle to be x.
∴ 30° + 45° + x = 180°.
x + 75° = 180°.
x = 180° - 75°.
x = 105°.
So, the measure of the third angle is 105°.

A math book consists of two sections: arithmetic and geometry in the ratio 5:3. How much of each type of content will be needed to make a book of 480 pages?
Answers
Answer:
As the ratio is 5:3, it totals 8 parts. I would do 480 divided by 8 to get the number of pages per part, then multiply that number into the ratio.
480 / 8 = 60
The value of each part being 60 put into the ratio 5:3 = 60x5 : 60x3

If Peter pays $84 to buy a watch after a discount of 30%, find the original price of the watch
Answers
(Original price) - 0.30p = 84
Let p = Original Price of the watch
p - 0.30p = 84
0.70p = 84
p = 84 ÷ 0.70
p = 120
The original price of the watch is $120.
Answer:
The original price was $120.
Step-by-step explanation:
Let the original price of the watch be w.
Then the discount is 0.30w and the discounted price is (1-0.30)w, or 0.70w.
Writing an equation in w, we get 0.70w = $84.
Solving this for w, we divide both sides by 0.70:
w = (84)/0.70 = $120
The original price was $120.

A recursive formula for the sequence 18, 9, 4.5, ... is
Answers
Answer:
Hope this image helps answer your question
and mark brainliest please.
The recursive formula is aₙ= aₙ₋₁ /2 for n > 1.
What is Recursive Formula?A recursive formula is a formula used to describe a sequence of numbers, where each term in the sequence is defined in terms of the preceding term(s). In other words, it is a formula that uses one or more of the previous terms in the sequence to generate the next term.
The recursive formula for a sequence gives a way to find any term of the sequence using the previous term(s).
To find the recursive formula for the sequence 18, 9, 4.5, ..., we need to look at how each term is related to the previous term.
We can see that each term is half of the previous term, so the recursive formula is:
a₁ = 18 (the first term is given)
aₙ= aₙ₋₁ /2 for n > 1
This means that to find the nth term of the sequence, we divide the (n-1)th term by 2. For example:
a_2 = a_1/2 = 18/2 = 9
a_3 = a_2/2 = 9/2 = 4.5
a_4 = a_3/2 = 4.5/2 = 2.25
and so on.

x = 7
Step-by-step explanation:
Given
4(5x - 2) = 2(9x + 3) ← distribute parenthesis on both sides
20x - 8 = 18x + 6 ( subtract 18x from both sides )
2x - 8 = 6 ( add 8 to both sides )
2x = 14 ( divide both sides by 2 )
x = 7
