Answer:
6
Step-by-step explanation:
The base of the triangle is 6.
This is because if the 2 given angles are 90, and 45, then that means that last angle must also be 45 because if you add all the angles of a triangle, it adds to 180.
To solve for x, also known as c, we do .
If, 36 + 36 = 72, Then x is the square root of 72, also known as D: 6
(as shown in the picture below)

Answer:
We get the value of x: x= 2
Step-by-step explanation:
Since the triangles are similar, the ratios of the lengths of corresponding sides are same.
We can use proportions to find the value of x
The proportion will be:
Now putting there values we can find value of x
We have:
BD = 6, DA = 4, BE = x+1, EC =x
Putting values
So, we get the value of x: x= 2
