How to do this question plz answer me ​

Mathematics
1 answer:
alexandr402 [8]2 years ago
5 0

Answer:

140

Step-by-step explanation:

We first find out how much degrees altogether in the pentagon so we do

S = (n-2) x 180

s is the sum in the shape

n is the number of sides

S = (5-2) x 180

S = 3 x 180

S =540

Now that we have the sum we can add all the sides, first lets make the side ABC = x and side BCD = 2x:

115 + 125 + 90 + x + 2x = 540

330 + 3x = 540

3x = 540 - 330

3x = 210

x = 70

Now that we know x = 70 we can find side BCD, it says its is 2 x angle ABC

so we do 2x70 = 140

so Angle BCD = 140

I hope i did this correctly.

The toy shop stocks tricycles and go-carts.
Mandarinka [93]

Total number of wheels in the toy shop = 37 wheels

Number of wheels for tricycles = 3

Number of wheels for go-carts = 5

  • Since the total number of tricycles and go-carts are not given, we solve this question using Assumption.

  • Let's assume: We have 4 tricycles and 4 go-carts

(4 x 3) + (4 x 5)

= 12 + 20

= 32 wheels. This assumption is wrong.

  • Let's assume: We have 4 tricycles and 5 go-carts

(4 x 3) + (5 x 5)

= 12 + 25

= 37 wheels. This assumption is correct.

Therefore, we have  4 tricycles and 5 go-carts in the toy shop.
