All angles in a triangle add up to 180°Step-by-step explanation:
Step 1: Set Up Equation
2v + 3v + 75 = 180
Step 2: Solve for v
Combine like terms: 5v + 75 = 180Isolate v term: 5v = 105Isolate v: v = 21Answer:
21 degrees
Step-by-step explanation:
3v + 2v + 75 = 108
3v + 2v = 5v
5v + 75 = 108

B) Dilations increase angle measures.
C) A dilated triangle is similar to the original triangle.
D) Dilations are a type of transformation
Answers
9514 1404 393
Answer:
B) Dilations increase angle measures.
Step-by-step explanation:
Dilations have no effect on angle measures, but they uniformly change the size and spacing of line segments. They are a non-rigid transformation that leaves geometric figures similar to the original.
The false statement is B.

24/13 or 1.8
Step-by-step explanation:

13b - 24 = 0
13b = 24
b = 24/13 or 1.8
Answer:
B = 6
Step-by-step explanation
1. (Do the parentheses) 3(6b-1)-7(2b+3) = 18b-3-14b-21
2. (Simplify) 18b-3-14b-21 = 4b-24
3. (Add 24 to both sides) 4b-24+24=0+24
4. (Simplify) 4b = 24

Answers
Answer:
x = 20
Step-by-step explanation:
The way to solve these problems is by isolating x (getting it by itself on one side).
So let's look at the operations needed! First of all, there's currently a +6 hanging out next to x. We don't want that, so we subtract 6 from both sides.
x/5 + 6 = 10
-6 -6
x/5 = 4
We now see that x is being divided by five. To get just x, we can now multiply both sides by five to get rid of that fraction.
x/5 = 4
*5 *5
x = 20

[tex]x = \frac{ \sqrt{6} }{2} [/tex]
[tex]y = \frac{3 \sqrt{2} }{2} [/tex]
Step-by-step explanation:
[tex] \sin(theta) = \frac{opposite}{hypotenuse} [/tex]
[tex] \cos(theta) = \frac{adjacent}{hypotenuse} [/tex]
[tex] \tan(theta) = \frac{opposite}{adjacent} [/tex]
theta = 30°
hypotenuse = √6
opposite = x
adjacent = y
1) find x using the sin formula[tex] \sin(theta) = \frac{opposite}{hypotenuse} [/tex]
[tex] \sin(30) = \frac{x}{ \sqrt{6} } [/tex]
[tex] \sin(30) \times \sqrt{6} = x[/tex]
[tex] \frac{ \sqrt{6} }{2} = x[/tex]
[tex]x = \frac{ \sqrt{6} }{2} [/tex]
2) find y using the cos formula[tex] \cos(theta) = \frac{adjacent}{hypotenuse} [/tex]
[tex] \cos(30) = \frac{y}{ \sqrt{6} } [/tex]
[tex] \cos(30) \times \sqrt{6} = y[/tex]

Step-by-step explanation:• When working with variables and numbers, you have to put the variables first (in alphabetical order) and then the numbers.
• To evaluate an algebraic expression, we find the value of the expression when the variable is replaced by a given number.
• To evaluate an expression, we substitute the given number for the variable in the expression and then simplify the expression using the order of operations.
• When we are not given a number for the variable in the expression, we have to group like-terms.
Example: 5x + 6 + 3x - 2 - y1st: group 5x and 3x (add the terms together) = 8x2nd: group 6 and -2 (add the terms together) = 43rd: Since -y has no like-terms, we can't group it = -yFourth, put the terms in order (variables = alphabetical order and then numbers) = 8x - y + 41. 4x + 12 - 3x + 8
4x - 3x = 1x = x12 + 8 = 20x + 202. -8x + 1 + 2x - 1 + 6x
-8x + 2x + 6x = -8x + 8x = 01 - 1 = 003. 4x - 3 - 2x - 5
4x - 2x = 2x-3 - 5 = -82x - 84. 100x + 5 - 5x + 5
100x - 5x = 95x5 + 5 = 1095x + 105. -4x - 4 - 2 - 5x
-4x - 5x = -9x-4 - 2 = -6-9x - 66. 2x - 1 + 2x - 4 + y
2x + 2x = 4x-1 - 4 = -54x + y - 57. 5y - x + 2y - y + 5
5y + 2y - y = 5y + 1y = 6y-x + 6y + 58. -15 + 3y - 3x - 2y + 4x
3y - 2y = 1y = y-3x + 4x = 1x = xx + y - 159. 4 - 3y + 3x - 2x - y

The population of Kenya was 45.1 million in 2009 and has been growing by 2.3% each year. If this trend continues, in what year will the population exceed 52.2 million?
Answers
Answer:
6.4294 years
Step-by-step explanation:
45.1 million in 2009 -- 2.3% each year
In what year will the population exceed 52.2 million?
We use exponential growth formula
ξ(t) = y = ab^t
a = 45.1, b = 1+ξ, ξ= 2.3%, ξ(t) = 52.2
52.2/45.1 = (1.023)^t
We take log both side
Log(1.15742794) = tlog(1.023)
0.0634939619 = t0.00987563371
t = 0.0634939619/0.00987563371
t = 6.429355701569454
t = 6.4294 years
