If two similar triangles have side lengths 3cm and 7cm then we can determine that the scale factor for the lengths is: 7/3
Now, we have to work out the area scale factor !
This is simple, since area is given in cm² then all we have to do is square our original scale factor!
So,
7/3² = 49/9
So, we can say that the ratio of the area would be:
x : 49/9x

Answer:
13
Step-by-step explanation:
13 right? all ya gotta do is add em together right?
1)Add up the numbers and variables.
2) Triangles equal 180 degrees.
3)Subtract the total of the numbers and 180.
4) Then divide by the variable.
X= -10

Answer:
The value of x to the nearest tenth is, 15.5 degree
Step-by-step explanation:
Given that: 
To find the value of x;
Take inverse of sin both sides we have;

Simplify:

Simplify:

Therefore, the value of x to the nearest tenth is, 15.5 degree
