Answer:
The measure of the 2 angles are 90° and 35°.
Step-by-step explanation:
The sum of angles in a triangle is 180°.
2x + x - 10 + 55 = 180
Simplify.
3x + 45 = 180
Find 3x.
3x = 180 - 45
= 135
Find x.
x = 135 ÷ 3
x = 45
2x° = 45° × 2
= 90°
(x-10)° = 45° - 10°
= 35°
Answer: x=45
Step-by-step explanation:
2 times 45 is equal to 90
45-10 is equal to 35
55+90+35=180
What is 2/19 as a percentage?
Give your answer rounded to one decimal place.
Answer:
10.53%
Step-by-step explanation:
The first step is to divide 2 by 19 to get the answer in decimal form: 2 / 19 = 0.1053 Then, we multiplied the answer from the first step by one hundred to get the answer as a percentage: 0.1053 * 100 = 10.53%
Answer:
11%
Step-by-step explanation:
Divide 2 by 19 and then move the decimal place twice to the right. It should be 10.5 but if rounded it becomes 11 so 11%

The area of a rectangle, A = 1•w is represented by the expression 24xBy15. Which could be the dimensions of the
rectangle?
O 2xy and 12xy?
O 6x?y and 4x® y5
O 10x®y 15 and 14x®y 15
O 9x4y11 and 12x2y4
Answer:
The length and width of the rectangle are: [tex]\mathbf{2x^5y^8\:and\: 12xy^7}[/tex]
Option A is correct.
Step-by-step explanation:
We are given: [tex]Area\:of\:rectangle=Length\times Width[/tex]
if [tex]Area = 24x^6y^{15}[/tex]we need to find the length and width of rectangle from options given.
Looking at the options, Option B,C and D are incorrect because multiplying the given lengths and widths, the area is not equal to [tex]24x^6y^{15}[/tex]
Only Option A gives us the result i,e
[tex]Area=2x^5y^8\times 12xy^7\\Area=24x^6y^{15}[/tex]
So, the length and width of the rectangle are: [tex]\mathbf{2x^5y^8\:and\: 12xy^7}[/tex]
Option A is correct.

the question is "what is the rate of change of the average height in feet of the trees on the farm with respect to the number of years since the trees were planted"
please help!
Answer:
Rate Of Change= 7
Step-by-step explanation:
all you have to do is see the difference, imma make a table here first
x y
1 10
3 24
6 45
11 80
15 108
from 10 to 24 you add 14
from 1 to 3 you add 2
so y/x
14/ 2 = 7
check:
from 24 to 45 you add 21
from 3 to 6 you add 3
so y/x
21/3 = 7
From y/x your final answer will always be 7.
So the rate of change will be 7.
Hope this helped a little!

which is the slowest rate? a. 2,983 km in 5 hr
b. 5,193 km in 7 hr
c. 3,094 km in 12 hr
d. 1,784 km in 3 hr
Answer:
C. 3,094 km in 12 hr
Step-by-step explanation:
we need to find kilometer per 1 hour so
2983/5=596.6 kilometers per hour
5,193/7= 741.857142857 km per hour
3,094/12=257.833333333 km per hour
1,784/3=594.666666667 km per hour

Find the length of the missing side
Answer:
52
Step-by-step explanation:
To solve, use the Pythagorean Theorem, which says c² = a² + b². Enter 20 as a and 48 as b and square them both. This will give you 400 for a, and 2304 as b. Add them to get 2704. So, c² = 2704. Find the square root of this to get 52. So, the third side is 52 in length.
in triangle, STU, ST = 52, and TU = 39. what is the range of values for the length third side
Answer:
The range of values for the third side is that;
x < 91
Step-by-step explanation:
For us to have a triangle formed, the length of the third side is smaller than the sum of the length of the two other sides
Mathematically;
Let us call the third side x
x < 52 + 39
x < 91

how do you find the perpendicular distance between a line segment and a point? (photo attached) i’m stuck
Answer:
Exact Distance = [tex]\frac{4\sqrt{10}}{5}[/tex]
Approximate Distance = 2.529822
============================================
Explanation:
This process is quite involved if you don't know the shortcut formula. I'll go over the long method first, and then show the shortcut in the next section.
First we'll need the equation of the line through points O and M. Use of the slope formula will show line OM has slope -1/3, which you are correct in stating.
Then use point slope form to determine the equation of line OM is y = (-1/3)x+11/3. This converts to the standard form x+3y = 11.
For anything in the form Ax+By = C, the equation perpendicular to this is of the form Bx-Ay = D. The A,B coefficients swap, and one item is negated. This helps form the negative reciprocal slope needed for the perpendicular line.
Compare x+3y = 11 to Ax+By = C. We see that A = 1 and B = 3.
So Bx-Ay = D turns into 3x-y = D. Then plug in the coordinates of H(-3,2) and compute to get
3x-y = 3(-3)-2 = -9-2 = -11. So D = -11
The equation 3x-y = D turns into 3x-y = -11 which is the equation of the line through point H and this line is perpendicular to line OM.
At this point, we have this system of equations
x+3y = 11
3x-y = -11
Solve that system however you wish. Substitution may be the best choice. Doing so leads to the intersection point (-2.2, 4.4)
The last step is to apply the distance formula between the points H(-3,2) and the intersection point (-2.2, 4.4)
The distance you should get is [tex]\frac{4\sqrt{10}}{5} \approx 2.529822[/tex]
I'm skipping steps because listing everything out would take up way too much space in my opinion.
--------------------------------------------------------
The first section goes over a fairly lengthy process of finding the perpendicular distance. Luckily, there's a shortcut.
Consider an equation of the form Ax+By=C, aka standard form. Now consider a point P located at (m,n) that is not on the line Ax+By = C. We can find the distance from P to the line using this formula below
[tex]d = \frac{|Am+Bn-C|}{\sqrt{A^2+B^2}}[/tex]
In this case, A = 1, B = 3 and C = 11 found back in the previous section. So you'll still need to calculate the equation of line OM.
Also, we'll use (m,n) = (-3,2) which are the coordinates of point H
From here it's a fairly straightforward computation
[tex]d = \frac{|Am+Bn-C|}{\sqrt{A^2+B^2}}\\\\d = \frac{|1*(-3)+3*2-11|}{\sqrt{(1)^2+(3)^2}}\\\\d = \frac{|-8|}{\sqrt{1+9}}\\\\d = \frac{8}{\sqrt{10}}\\\\[/tex]
Optionally we can rationalize the denominator like so
[tex]d = \frac{8}{\sqrt{10}}\\\\d = \frac{8\sqrt{10}}{\sqrt{10}\sqrt{10}}\\\\d = \frac{8\sqrt{10}}{\sqrt{10*10}}\\\\d = \frac{8\sqrt{10}}{\sqrt{100}}\\\\d = \frac{8\sqrt{10}}{10}\\\\d = \frac{2*4\sqrt{10}}{2*5}\\\\d = \frac{4\sqrt{10}}{5}\\\\d \approx 2.529822\\\\[/tex]
There are different ways to write down the answer, but they all represent the same number.
