Using A^2+B^2=C^2
12^2+5^2=169
Hypotenuse= 13

Sin(Ø)= 5/13
Cos(Ø)= 12/13
Tan(Ø)= 5/12

csc(Ø)=13/5
sec(Ø)=13/12
cot(Ø)=12/5

Answer:

Part 1) sin(\beta)=\frac{5}{13}

Part 2) cos(\beta)=\frac{12}{13}

Part 3) tan(\beta)=\frac{5}{12}

Part 4) cot(\beta)=\frac{12}{5}

Part 5) sec(\beta)=\frac{13}{12}

Part 6) csc(\beta)=\frac{13}{5}

Step-by-step explanation:

see the attached figure to better understand the problem

In the right triangle ABC

we have

AC=12\ units, BC=5\ units

Applying the Pythagoras Theorem

Find the length side AB (hypotenuse)

AB^{2}=AC^{2}+BC^{2}

substitute the values

AB^{2}=12^{2}+5^{2}

AB^{2}=169}

AB=13\ units

Part 1) Find the sin(\beta)

sin(\beta)=\frac{BC}{AB}

substitute the values

sin(\beta)=\frac{5}{13}

Part 2) Find the cos(\beta)

cos(\beta)=\frac{AC}{AB}

substitute the values

cos(\beta)=\frac{12}{13}

Part 3) Find the tan(\beta)

tan(\beta)=\frac{BC}{AC}

substitute the values

tan(\beta)=\frac{5}{12}

Part 4) Find the cot(\beta)

cot(\beta)=\frac{AC}{BC}

substitute the values

cotan(\beta)=\frac{12}{5}

Part 5) Find the sec(\beta)

sec(\beta)=\frac{1}{cos(\beta)}

substitute the values

sec(\beta)=\frac{13}{12}

Part 6) Find the csc(\beta)

csc(\beta)=\frac{1}{sin(\beta)}

substitute the values

csc(\beta)=\frac{13}{5}

What is 13.8924439894 rounded to the nearest tenth
gogolik [260]
1st decimal place=tenth
2nd=hundreth

to round, you look at the place after it
so 13.8924439894 to tenth
look untill hundreth
13.89
if hundreth<u>></u>5, round tenth up
if hundreth place<5 leave tenth as is

13.89
9<u>></u>5
round up
8+1=9
13.9 is to theh tenth

Answer:

Yes, the triangles are similar by SAS

Step-by-step explanation:

Looking at the picture, we see that there are two triangles with side lengths of different sides. We can deduce that the scale factor is 1 2/3, because 8 divided by 4.8 is 1 2/3, and 10 divided by 6 is the same. Now that we have clarified that the triangles share the same scale factor, we notice that the angle is also the same, as mentioned in the picture. This leads us to say that the triangles are similar by the SAS similarity theorem (Side, Angle, Side). I hope this helped and please don't hesitate to reach out with more questions!

marissa [1.9K]

Answer:

A. 75

Step-by-step explanation:

to get the average mark multiply the result by it's associated weight

93 × 10% = 9.3

82 × 30% = 24.6

72 × 40% = 28.8

60 × 20% = 12

then add these numbers to get his average 74.7 which is closest to 75
