Angels ABC and DEF are supplementary angles. The measure of angle ABC, in degrees, is given by the expression 2x + 10. The measure of angle DEF, in degrees, is given by the expression 3x - 15. What is the value of x?

Answers

Answer 1

Answer:

x = 31°

Step-by-step explanation:

Recall ;

Supplemtary angles summ up to 180°

Given that :

ABC and DEF are Supplementary angles and hence sum up to 180°

ABC + DEF = 180°

(2x + 10) + (3x + 15) = 180

2x + 10 + 3x + 15 = 180

2x + 3x + 10 + 15 = 180°

5x + 25° = 180°

5x = 180 - 25

5x = 155

x = 155 / 5

x = 31°

In circle O below AB is a diameter and m

Answers

The measure of arc AC is 40°
Step-by-step explanation:
In any circle the measure of an inscribed angle is one-half the measure of its subtended arc
In circle O
∵ ∠BAC is an inscribed angle subtended by arc BC
∴ m∠BAC = m arc BC
∵ m∠BAC = 70°
- Substitute it in the the expression above
∴ 70 = m arc BC
- Multiply both sides by 2
∴ 140 = m arc BC
∴ The measure of arc BC is 140°
∵ AB is a diameter
- The diameter divides the circle into two equal arcs
∴ m of arc ACB = measure of the circle
- The measure of the circle is 360°
∴ m of arc ACB = (360°)
∴ m of arc ACB = 180°
∵ m arc BC + m arc AC = m arc ACB
∴ 140° + m arc AC = 180°
- Subtract 140 from both sides
∴ m arc AC = 40°
The measure of arc AC is 40°

Answers

Answer:

the difference of the mean in the case of mean absolute deviation is 2.5

Step-by-step explanation:

The computation of the difference of the mean is shown below:

Difference is of

= B - A

= 47 - 42

= 5

Now the difference of the mean is

= 5 ÷ 2.5

= 2.5

Hence, the difference of the mean in the case of mean absolute deviation is 2.5

An uber charges a flat rate of $6 plus $1.25 per mile. Kayla can spend no more than $27.50. If she wants to tip her driver $4, what is the greatest number of miles she can uber?

Answers

Answer:

14

Step-by-step explanation:

to determine the answer

Subtract the amount she wants to tip from the total amount of money she wants to spend

$27.50 - $4 = $23.50

Let m = total miles

the total miles she intends to drive can be determined using this equation

$23.50 = $6 + $1.25m

Collect like terms

$23.50 - $6 = $1.25m

$17.50 = £1.25m

Solve for m

17.50 / 1.25 = 14

okay lets begin with the first part of it which is tan

sinx=p/h -----> some people have  

cosx=b/h ----> curly brown hair  

tanx=p/b -----> through proper brushing

an easy way to remember the ratios ^

we have sin and cos so we can say that the h=41 b= 40 and p is 9

so tan will be [tex]tanA=\frac{9}{40}[/tex]

now csc sec and cot are reciprocals of sin cos and tan

so sinA is 9/41 cscA will be 41/9

cosA is 40/41 secA will be 41/40

tanA is 40/9 cotA will be 40/0
