Answer:
let the unknown angle be x
we know. sum of angles of a triangle is 180°
so,
130+20+x=180
150+x=180
x=180-150
x=30°

Ill mark brainliest if yall help me and ill make it 20 points
Answers
15 = 5x + 10
15 - 10 = 5x + 10 - 10
5 = 5x
5/5 = 5x/5
1 = x
2) 5n + 34 = -21(1-7n)
5n + 34 = -21 + 147n
5n + 34 = -21 + 147n
5n - 147n + 34 = -21 + 147n - 147n
-142n + 34 = -21
-142n + 34 - 34 = -21 - 34
-142n = -55
-142n/-142 = -55/-142
n = 55/142

T, U, and V are
collinear. Suppose
U is between T and
V and that the
following is true:
TU = 7x - 4,
UV = 6x + 10, and
TV = 45.
Find TU.
Answers
The value of TU is 17.
Here,
T, U, and V are collinear.
U is between T and V
TU = 7x - 4,
UV = 6x + 10, and
TV = 45.
We have to find TU.
What are collinear points?
Three or more points are said to be collinear if they are lie on a single straight line.
Now,
T, U, and V are collinear.
U is between T and V
TU = 7x - 4,
UV = 6x + 10, and
TV = 45.
Clearly, TU + UV = TV
After putting the given values we get;
TU + UV = TV
(7x - 4) + (6x + 10) = 45
13x + 6 = 45
13x = 45 - 6
13x = 39
x = 3
Hence, TU = 7x - 4 = 7 * 3 - 4 = 21 - 4 = 17
So, The value of TU is 17.

QUESTION 10 of 10: You pay $1,000 for your insurance policy that covers up to $1 million in losses. If the insurance company just broke even
on similar policies, which of the following is closest to the odds the insurance company assumes for your making a claim of $1 million?
оооо
O a) 1 in 2
Ob) 1 in 5
c) 1 in 50
d) 1 in 1,000
Answers
Answer:
It's D - 1 in 1,000
Step-by-step explanation:
If the company breaks even, it collects $1,000,000 and pays out $1,000,000. If it collects $1,000 from each company, that means it sold $1,000,000 / $1,000 = 1,000 policies, and it paid out on one of them. This means the expected odds are 1 in 1,000.
The one which is closest to the odds the insurance company assumes for your claiming $1 million is 1 in 1000. Hence, option D is correct.
What are arithmetic operations?The four basic operations of arithmetic can be used to add, subtract, multiply, or divide two or even more quantities.
They cover topics like the study of integers and the order of operations, which are relevant to all other areas of mathematics including algebra, data processing, and geometry.
As per the given data in the question,
If the business is profitable, it will receive $1,000,000 and spend $1,000,000.
If it receives $1,000 from each business, it has sold,
$1,000,000 / $1,000 = 1,000 policies, and one of them saw a payout.
This indicates that the likelihood is 1 in 1,000.

Find the area of the triangle.
Answers
Answer:
66cm²
Step-by-step explanation:
The figure shown is actually a parallelogram
The area of a parallelogram can easily be calculated by multiplying the base length by the height
For this parallelogram the height given is 6 cm and the base length given is 11cm
so area = 6 * 11
6 * 11 = 66
hence the area of the parallelogram is 66cm²

Math honestly shouldn't exist-
Answers
Answer:
This isn't really that hard... ∠A = 166°
Step-by-step explanation:
Because ∠A and ∠B are corresponding angles of a set of parallel lines, that means they are equal, so you can use this equation to solve for x:[tex]7x+40=3x+112[/tex] ⇒ [tex]4x=72[/tex] ⇒ [tex]x=18[/tex]. To find ∠A, just substitute x for 18 and you'll get that ∠A equals 7 * 18 + 40 = 126 + 40 = 166°.

The floor of a storage unit in the shape
of a rectangular prism has an area of 106 1/4 square feet. The height of the storage unit is 7 1/2 feet. What is the volume of the storage unit?
A. 742 1/8ft B. 744 1/4 ft C. 795 1/4 ft D. 796 7/8 ft
Answers
Answer:
V = 796 7/8 ft^3
Step-by-step explanation:
The storage unit has a rectangular shape.
Thus, the volume is V = (area of floor)(height)
V = (106 1/4 ft^2)(7 1/2 ft)
V = 796 7/8 ft^3
Converting 106 1/4 ft to 106.25 makes it easier to use a calculator here. Same with 7 1/2 ft: 7.5 ft
