Answer:
Step-by-step explanation: To write two triangles are congruent you need to draw three lines. So, (first triangle) an equals sign with one extra line underneath and then the last triangle.
10(x+9)-x
Distribute
10x+90-x
9x+90
There it depends what it is equal to
For example 10(x+9)=x
Or 10(x+9)-x=0
Answer:
The value of x is 13°
Step-by-step explanation:
<u>Given:</u> m || n
For a straight line = 180°
Now, by exterior angle
(7x - 1)° + (8x - 14)° = 180°
7x - 1° + 8x - 14° = 180°
15x - 15° = 180°
Now, add 15° both side we get,
15x - 15° + 15° = 180° + 15°
15x = 195°
Now, divide both side by 15
15x/15 = 195°/15
x = 13°
Thus, The value of x is 13°

Answer:
3/50.
Step-by-step explanation:
There are 10 marbles in the bag.
Probability( a green marble) = 2/10 = 1/5.
Now we replace the green marble in the bag so it contains 10 marbles again.
Probabilty(a yellow marble) = 3/10.
So Probability(Choosing a green then a red with repeacemen)
= 1/5 * 3/10
= 3/50.
