Answer:

104

Step-by-step explanation:

ok so to find the area of this triangle you need to use the number you have witch are 16 and 13 so we wana find the area of one side of the triangle witch it has mark ware it needs to be split and so 16 / 2 is 8 and so we have 2 pairs of 8 and now you multiply hight by width and get 8 x 13 is 104 so we devide that by two in order to get one section of the triandle so 104 / 2 is 52 and thats one side of the triangle and now we add 52 by 52 and get 104

Answer:

$3450

Step-by-step explanation:

Here, P = $3000, N = 1.5 years, R = 10%

$SI = \frac{PNR}{100} \\ \\ SI = \frac{3000 \times 1.5 \times 10}{100} \\ \\ SI = 450 \\ \\$

Amount of down payment

= $3000 + $450

= $3450

Another one! This is so annoying! thank u all who are actually helping me

Gemiola [76]

Answer:

10cm

Step-by-step explanation:

find the diameter of the circumference of 5cm:

d= c÷3.14

=5cm÷3.14

=1.6cm

Double 1.6cm:

1.6×2= 3.2

Find the new cicumference:

c= 3.14×d

= 3.14×3.2

= 10cm

Answer:

The size of angle AFE (or Angle F) is 162º.

Step-by-step explanation:

A hexagon's angles add up to 720º. Since there is one line of symmetry (straight down the middle), angle A is the same as angle B; 117º, also known as X. This means angle F is equal to angle C, and angle E is equal to angle D. Angles A and B are to be represented by X. Angles F and C are to be represented by Y. Angles E and D are to be represented by Z. We need to find the remaining sum of the unknown angles: 720 - (117 • 2) = 486º. In the given information, angles BCD (y) is equal to 2 • angle CDE (z). In other words, y = 2z. There are 2y; to convert 2y into z's, we multiply y's equal of z by 2 to get 4z. 2y = 4z. Now we can write an equation to solve: (720 - 2x) ÷ (4z + 2z) = z. Where x is 117º. First we solve part 1:

720 - 2(117) = ?

720 - 234 = 486º

Rewrite the equation: 486 ÷ (4z + 2z) = z. That's not how I want to solve it, so I'm rewriting it again as 486 = 4z + 2z. Now to solve it:

Solve for z (Part 2):

486 = 4z + 2z

486 = 6z Combine like terms

----------------------------------------------------------------------

Long division:

081

6 |486

- 0↓

- 48↓

- 6

----------------------------------------------------------------------

81 = z Divide both sides by 6

Solve for y:

y = 2z

y = 2(81) Plug 81 in for z

y = 162

Checking my work:

720 = 2x + 2y + 2z

720 = 2(117) + 2(162) + 2(81) 117 = x; 162 = y; 81 = z

720 = 234 + 324 + 162 Simplify

720 = 720 Add

Woop woop!! We're almost done!

Remember the question is asking us to "work out the size of angle AFE" (or angle F for short). Angle F is represented by y, so we simply look for where we solved for y and see that y(AFE) = 162.
