Answer 1

Answer:

in right angled triangle MNO

relationship between base and hypotenuse is given by cos angle

cosx°=b/h

cosx°=OM/MN

x°=cos-1(26/99)=74.77=74.8°

Answer 2

Answer:

∠ M ≈ 74.8°

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos M = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{OM}{MN}[/tex] = [tex]\frac{26}{99}[/tex] , then

∠ M = [tex]cos^{-1}[/tex] ([tex]\frac{26}{99}[/tex] ) ≈ 74.8° ( to the nearest tenth )

Answers

Answer:

9.916...

Step-by-step explanation: (The "6" is repeating)

Divide using long division. The whole number portion will be the number of times the denominator of the original fraction divides evenly into the numerator of the original fraction, and the fraction portion of the mixed number will be the remainder of the original fraction division over the denominator of the original fraction.

This gives us a mixed number-fraction: 9 and 11/12.

If we then turn this into a simplified fraction, then it becomes 119/12. Turn that into a decimal by dividing the numerator by the denominator.

This gives us our answer of 9.916...!!! Hope that helps!

Researchers once surveyed college students on their Face book use. The following two-way table displays data for the sample of students who responded to the survey.
How many students in the survey were in the age category of 18 to 22?
_____ students.

Answers

Answer:

82

Explanation:

78 respondents aged 18 to 22 use face book and 4 respondents aged 18 to 22 do not use face book. since there are no other options for the survey, the total number of students who were surveyed that are aged 18 to 22 would be 78 + 4 = 82.

i hope this helps! :D

The number of students in the age category of 18 to 22 is 82.

Using the two - way table Given ;

The Number of students in the age category of 18 to 22 include :

(Number of those who use fb + number of those who do not use Fb)

Number who uses Fb = 78

= 78Number who do not use Fb = 4

Hence, The Total number surveyed between age 18 to 22 = (78 + 4) = 82.

whar are the formulae of - sin , tan , cosec, cos​

Answers

Answer:

Now, the formulas for other trigonometry ratios are: Cot θ = 1/tan θ = Adjacent side/ Side opposite = AB/BC. Sec θ = 1/Cos θ = Hypotenuse / Adjacent side = AC / AB. Cosec θ = 1/Sin θ = Hypotenuse / Side opposite = AC /BC

Sin=Opposite/Hypotenuse
Tan=Opposite/Adjacent
Cosec=Hypotenuse/Opposite

Given right triangle ABC with altitude BD drawn to hypotenuse AC. If AB=8 and AD=4, what is the length of AC?

Answers

Answer:

AC = 16

Step-by-step explanation:

In ΔABC & ΔABD

angle ABC = angle ADB ---- (each 90°)

angle BAD = angle CAB ---- (common)

so, therefore

ΔABC ~ ΔABD --- (by AA similarity)

by similarity in ΔABC & ΔABD

AB/AC = AD/AB

8/AC = 4/8

AC = 8×8÷4

AC = 16
