SA = (12 x 5 x 2) + (20 x 5 x 2) + (12 x 20) + (0.5 x 12 x 9 x 2) + (20 x 11 x 2)

SA = 120 + 200 + 240 + 108 + 440

SA = 1,108 in²

The answer you got was incorrect.

Provides a unique set of guidelines that can be applied to any triangle. The guidelines demonstrate a clear understanding of app

Oksi-84 [34.3K]

we can have a triangle and we know that there are two angles.

30º and a 45º + 105 =180º angle. applying the sides.

therefore if we have the whole triangle completed we have a constant triangle.

so it tell us we can you’se SOH CAH TOA

we can varrify what kind of triangle we are using.

for example if we were to use Sin I would do

Sin 30/ 2 = sin of 105º/ A = sin=45º/ B

if you would want to solve for sin 30/2 and sin 105, then we solve.

or Sin 30/2 and Sin 105 as well.

with your calculator use sin= 30=.5 and use sin 105º a divide by 1.5 on both sides 1.5= A /sin 105º * 1.5 answer would be 3.86. a is = to 3.86 (Not the answer)

$\bold{2x - 15 = 5 - 3x} \\ \bold{2x + 3x = 15 + 5} \\ \bold{5x =20 } \\ \bold{x = \cancel{ \frac {20}{5} }} \\ \bold{x = 4}$

Hope it helps

Which sets of ordered pairs represent functions from A to B? (Select all that apply.) A = {a, b, c} and B = {3, 4, 5, 6}

sesenic [268]

Answer:

See Explanation

Step-by-step explanation:

The question has mission options; However, the question is still solvable.

Given

$A = \{a,b,c\}$

$B = \{3,4,5,6\}$

Required

Determine possible ordered pairs of A to B

A function is of the form (x,y)

Let A be the range of the function and B, the domain

Let (x,y) be a function of A to B, where x represents any of the values in A sets and y represents any of the values in B

A ordered pair can only be regarded as a function if and only if it has unique y-values

Hence, a possible ordered pair is:

$(A,B) = \{(a,3),(b,4),(c,5)\}$

Another possible ordered pair is

$(A,B) = \{(a,4),(b,5),(c,6)\}$

Note that there as as many as possible ordered pair as long as the y-values are unique
