Answer:
P = 131 degrees
Step-by-step explanation:
We know that the sum of the interior angles of a triangle is 180 degrees
The exterior angles shown form a straight line with the corresponding interior angle
So the two interior angles can be calculated
The sum of two angles on a straight line is 180 degrees
By subtracting the exterior angles from 180, we can get the two interior angles which we can add to the angle at P to give 180
Thus;
P + (180-162) + (180-149) = 180
P + 18 + 31 = 180
P = 180-31-18
P = 131

So visually youre given the function
for h(-4) it can also be written as h(-4) = y
what do you get for y when you substitute - 4 for x?
All you have to do is trace the line until you get to x=-4 and then find the y that corresponds to it (looks like around y= - 1)
for the other one h(x) = - 5
what do you get for x when you substitute - 5 for y?
what you do is similar, trace the line along the y-axis and see what x-value you get for y =-5
Answer:
3 and x = 0
Step-by-step explanation:
To find the value of h(- 4)
Locate x = - 4 on the x- axis, go vertically up to meet the graph at (- 4, 3 )
Then the value of h(- 4) = 3
For h(x) = - 5
Locate y = - 5 on the y- axis. This is the point (0, - 5)
then the value of x for which h(x) = - 5 is x = 0

The ages of trees in a forest are normally distributed with a mean of 25 years and a standard deviation of 5 years.
Answers
Complete question is in comment section :
Answer:
68%
Step-by-step explanation:
Mean = 25
Standard deviation = 5
The percentage of trees between 20 and 30
20 trees = 1 standard deviation below the mean ; mean - 1(standard deviation)
25 - 5 = 20
30 trees = 1 standard deviation above the mean ;
Mean + 1(standard deviation) ;
25 + 5 = 30
This means, 20 and 30 lies ±1 standard deviation from the mean which according to the empirical rule is 68%

A track is 400 yards around how many full laps does tyler need to run if he wants to run atleast 2 milies
Answers
Answer:
17.6 laps
Step-by-step explanation:
Total distance to be covered = 2 miles
distance coved in each lap = 400 yards
We know that 1 mile = 1760 yards
therefore, 4 miles will make = 4×1760
= 7040 yards.
Number of laps to be taken
= Total distance to be covered ÷ distance coved in each lap
= 7040/400 = 17.6 laps
Therefore, it would take 17.6 laps to cover a distance of 4 miles if lap were 400 yards.
Line segment TU has endpoints (-7,10) and (-6,-5). What is the length of TU to the NEAREST TENTH?
Answers
Answer: 15 units
Step-by-step explanation:
Given
The endpoints of the line segment are [tex](-7,10)\ \text{and}\ (-6,-5)[/tex]
The length of the line segment is given by the distance formula i.e.
[tex]d=\sqrt{\left( x_2-x_1\right)^2+\left( y_2-y_1\right)^2}[/tex]
Insert the values,
[tex]\Rightarrow d=\sqrt{\left( -6+7\right)^2+\left( -5-10\right)^2}\\\Rightarrow d=\sqrt{1^2+\left( -15\right)^2}\\\Rightarrow d=\sqrt{1+225}\\\Rightarrow d=15.0\ \text{units}[/tex]
Therefore, the length of line segment TU is 15 units

A man travels in a taxi for 12.2 miles.
What is the cost of his journey?
Show your working
Answers
Answer:
£23.30
Step-by-step explanation:
First, find the cost from traveling 12.2 miles. Since the cost is £1.50 per mile, multiply 12.2 by 1.5:
12.2(1.5)
= 18.3
Add the standing charge to this:
18.3 + 5
= 23.3
So, the cost of his journey is £23.30

1. tan(x) = 9/20
arctan(9/20) ≈ 24.23°
2. cos(x) = 17/32
arccos(17/32) ≈ 57.91°
3. tan(x) = 13/18
arctan ≈ 35.84°
4. sin(x) = 21/28
arcsin(21/28) ≈ 48.59°
Answer:
1 x = 24.2°
2 x = 57.9°
Step-by-step explanation:
You must memorize the definitions of the trig functions and then these problems are easy
1: tan = opposite side/adjacent side
opp side to x is 9 and adjacent side is 20
So, tan x = 9/20
x = arctan (9/20) = 24.2°
2: cos = adjacent side/hypotenuse
adjacent side = 17 and hypotenuse = 32
cos x = 17/32
x = arccos (17/32)
x = 57.9°
You do 3 and 4. Hint: Use the tan function in 3 and the sine function in 4

The measure of an angle is 2.8.what is the measure of its complementary angle
Answers
Answer:
87.2º
Step-by-step explanation:
Complimentary angles total 90º
c + 2.8 = 90
c = 90 - 2.8
c = 87.2º
Answer:
87.2°Step-by-step explanation:
When angles are complementary, it means that they both add up to 90°.
In this case, one of the angles measures 2.8°.
So, to find the other one, we subtract 2.8 from 90.
90 - 2.8 = 87.2
The measure of the complementary angle is 87.2°
