Answer: 81 sqare root is 9 so its 9

vichka [17]2 years ago

Answer:
9

Step-by-step explanation:

We can use the Pythagorean Theorem for this because it's a right triangle. We have b and c, we just need a.


So, a^2+12^2=15^2

Which we can make a^2+144=225.

We can then subtract to get a^2=81

To get a by itself, you have to find the square root of 81, which is 9.

a=9

Find the value of x.<br>m&lt;2= 10x + 10<br>​
Gekata [30.6K]

Answer:

The answer to your question is x = 3

Step-by-step explanation:

Data

m∠2 = 10x + 10

exterior angle = 110°

x = ?

Process

1.- Find the measure of the angle supplementary to the angle 110°. It will be angle y.

    180° = 110° + y

- Solve for y

     y = 180 - 110

     y = 70

2.- From the picture we conclude that the triangle is Isosceles because two of its sides measure the same.

In an Isosceles triangle two of its angles measure the same so,

       180° = 70° + 70° + ∠2

- Solve for ∠2

       ∠2 = 180 - 70 - 70

       ∠2 = 40

3.- Find x

      10x + 10 = 40

Solve for x

      10x = 40 - 10

      10x = 30

          x = 30/10

          x = 3

a=206

206=3+(s/2)
minus 3 both sides
203=s/2
times 2/1 both sides
406=s

sabrina=406
to check

206=3+(406/2)
206=3+(203)
206=206
