Step-by-step explanation:

Answer:

79°

Step-by-step explanation:

its a right angled triangle so the unknown is 90°

180 - (90 + 11)

Answer:

84, -6

Step-by-step explanation:

y= -x+84

y= x^2+(-6)

The system of equations used to find the value of x is:

y = -x + 84

y = x² - 6

Let x represent the first number and y represent the second number.

The sum of the two numbers is 84, hence:

x + y = 84

y = -x + 84      (1)

The square of the first number is 6 more than the second number. Hence:

x² = 6 + y

y = x² - 6     (2)

The system of equations used to find the value of x is:

y = -x + 84

y = x² - 6

Answer:

67.5 in³

Step-by-step explanation:

Given that :

Volume 1 = 540 in³

Volume 2 of similar shape = x ; if the scale factor = 1/2

Volume of a shape = length * width * height)

The scale factor = 1/2

Volumetric factor = 1/2 * 1/2 * 1/2 = 1/8

Hence, the volume of similar sculpture will be :

540 in³ * 1/8 = 67.5 in³

Answer:

relationship between base and perpendicular is

given by tan angle

tan x=P/h

remember perpendicular is opposite side of taken angle

tan x=13/8

<x=tàn-¹(13/8)=58.39°

for second one

relationship between base and hypotenuse is given by cos angle

cos G=b/h

cos G=24/32

Answer:

x = 15

Step-by-step explanation:

Create and solve an equation of ratios.  We can do this because the smaller triangle and the larger one are similar.

  x          5 + x

------- = -----------

   9         9 + 3

Cross-multiplying, we get 12x = 45 + 9x,

which simplifies to 3x = 45

Solving for x, we get x = 15

Answer:

48

Step-by-step explanation:

First, we find 20% of 60. That is 12. Then we subtract 12 from 60, making 48.

Answer:

Step-by-step explanation:

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

we can find angle C  b/c the angles of a triangle always add to 180 , soo

180= C + 81 +63.5

35.5 = C

now that we have angle C and we know the Hyp we can use sin to find side g

where g = Opp and Hpy = 13.8 for this question

Sin(35.5) = Opp / 13.8

13.8*Sin(35.5) = Opp

8.0137 = Opp

g = 8.0137

next they ask for the area of the biggest triangle  ABC ( there are two smaller ones when you use D )

we can use 1/2 * base * height , but we don't know the base yet, even thou we do know the height.  

we can solve for line segment CD and DB and then add them for the side a .. or the base of the biggest triangle sooo.. CD = adj

Cos(35.5) = Adj / 13.8

13.8*Cos(35.5) = Adj

11.234794 =Adj

now solve for DB using cos again but with the other smaller triangle where  Adj = DB now

Cos(63.5) = Adj / 8.9

8.9*Cos(63.5) = Adj

3.971160

add these two Adjs together to get the total  'a' side

15.205954

now plug in side a as the base and g as the height of our biggest triangle

Area = 1/2 * 15.205954 * 8.0137

Area = 60.9159

rounded to 2 sig figs

Area = 60.92   :)   hope you get an "A"    :P

Answer:

43x+39

Step-by-step explanation:

(5)(9x)+(5)(6)+−2x+9

=45x+30+−2x+9

=45x+30+−2x+9

=(45x+−2x)+(30+9)

=43x+39

(if this helps please give brainliest and 5 stars thanks)

Answer:

43x + 39

Step-by-step explanation:

5 ( 9x + 6 ) - 2x + 9

Firstly, open up the brackets.

= 45x + 30 - 2x + 9

Now bring the like term together and simplify.

=45x - 2x + 30 + 9

= 43x + 39
