How do I find the length of AB

Mathematics
2 answers:
Dmitrij [34]3 years ago
5 0

hello

now we know that this is a vertical triangle.

if C = 90° and B = 12°

90+12 = 102 180-102=78.

so A = 78°

now look at the A. A is looking to the CB.

so we can set up an equal.

A is 44

and

B is ?

if 78 is 44

12 is x 12×44÷78= 6.7692..

right now

AC = 6.7692

BC is = 44

this is a vertical triangle thats why the verticals angle's lookings (AB) square, should be the others lookings squares sum.

6.7692^2 = 45.2875..

44^2 = 1936

1936+45.2875= 1981.2875

now im taking 1981.2875 into the square root to find AB.

✓1981.2875 = 44.5

there were many numbers after the 1981 thats why it will probably 44.9

good luckk

Find each function value.
Levart [38]

Put the values of x to the equations of the functions:

1. f(9) → x = 9; f(x) = -3x + 10

f(9) = -3(9) + 10 = -27 + 10 = -17

2. f(-2) → x = -2; f(x) = 4x - 1

f(-2) = 4(-2) - 1 = -8 - 1 = -9

3. f(-5) → x = -5; f(x) = -2x + 8

f(-5) = -2(-5) + 8 = 10 + 8 = 18

Please help me on this problem I don't know how to do it.
quester [9]
1: establish the angles, basically label one x (the small one) and the other y (the bigger one)

2. supplementary angles add up to 180, so therefore you have the equation x + y = 180.

3. so y (the bigger one) is 8 less than 3 times the smaller one (x) therefore you come up with the equation y = 3x - 8

4. plug in the equation of the bigger one into the other equation

x + 3x - 8 = 180
(combine like terms)
4x - 8 = 180

5. solve the equation by adding 8 to 180, then by dividing by 4.
x should equal 47

6. plug in 47 into the x + y = 180 equation, subtract 47 from 180 and you end up with 133

i hope i explained it alright

The volume of an oblique pyramid with a square base is V units3 and the height is h units. Which expression represents the area
givi [52]

Answer:

Area of the base of the pyramid = V/h

Step-by-step explanation:

Mathematically, we know that the volume of the pyramid can be calculated by multiplying the area of the base by the height of the pyramid

Now using the variables in the question;

V = area of base * height of pyramid

Area of base = V/height of pyramid

Area of base = V/h
