Answer:
Step-by-step explanation:
The picture of the question in the attached figure
we know that
The triangle ABD is an isosceles triangle
because
AB=BD
The segment BM is a perpendicular bisector segment AD
so
<em>In the right triangle ABM</em>
Applying the Pythagorean Theorem
we have
substitute
-----> equation A
<em>In the right triangle BMC</em>
Applying the Pythagorean Theorem
we have
substitute
----> equation B
equate equation A and equation B
solve for x
Simplify
<em>Find the length of DC</em>
substitute the given values
Answer:
x=4
Step-by-step explanation:
The left and right sides are equal so:
5x-2 + 4x = 7x-4 + x+6
Collect the like terms and calculate the sum :
9x-2 = 8x+2
Move terms and change it's sign:
9x-8x = 2+2
And finally:
x=4
Also if you solve the equations of the other sides you'll find x₁=0.5 and x₂=4
which the intersection with the previous answer will be x=4
Answer:
340cm squared
Step-by-step explanation:
30*10 = 300
30-25 = 5
18-10 = 8
5*8 = 40
300+40 = 340
