Answer:

a. 3x = 45

15cm

Step-by-step explanation:

Given the perimeter of an equilateral triangle = 45cm .

Using the equation

3x = 45

Divide both sides by 3

x = 45/3

= 15cm

The length of each side of the triangle is 15cm because an equilateral triangle has its three sides equal

Help with this problem please!

1. To solve for x, you can see that nearby C and D, the two angles are equal. We can ,therefore, make an equation and solve it:
5x - 29 = 3x + 19
- 3x
2x - 29 = 19
+ 29
2x = 48
÷ 2
x = 24

2. So for this part you would substitute the value of x and then minus that angle from 180:
3 × 24 = 72
72 + 7 = 79°
180 - 79 = 101° = ∠1

3. 180 = 101 = 79° = ∠2

4. 180 - 79 = 101° = ∠3

5. Angle 4 is equal to angle 3 because there is an alternate angle (z angle) so 101° = ∠4

6. 180 - 101 = 79° = ∠5

7.  180 - 101 = 79° = ∠6

8. To find angle 7, you have to substitute in x again, so:
5 × 24 = 120
120 - 29 = 91
180 - 91 = 89° = ∠7

9. Angle 8 is the same as angle 7 because they are opposite angles, so 89° = ∠8

10. Angles 2 and 3 are supplementary, which means they add up to 180°.

I hope this helps! :)

AleksAgata [21]

Answer:

60 times

Step-by-step explanation:

The numbers are 1, 2, 3, 4, 5, 6

1, 3, and 5 are odd

therefore half the numbers are odd

therefore there is a 50% chance she will get an odd number

50% * 120 = 60

so the answer is 60
