Answer:
Right option is (D).
ΔABC and ΔDBE are similar triangles by side angle side similarity postulate.
Step-by-step explanation:
We have given,
Two triangles ΔABC and ΔDBE such as :
This relation will contribute to side side similarity.
Also,
∠B = ∠B , This will contribute as an angle similarity .
So combining above two relations,
and ∠B = ∠B
we can conclude that the triangle ΔABC and ΔDBE are similar triangles by side angle side similarity postulate.
Hence the right option is (C)
Answer:
<em>(B). 319 </em>
Step-by-step explanation:
=
=
x = ≈ <em>319</em>
The Pythagorean theorem is: a²+b²=c², and "c" will always be the hypotenuse or the longest side of the triangle.
In order to find MN you can make a triangle, and then you can find the lengths of the other sides(a and b).
You should get a = 4 and b = 6. Next you plug these numbers into the equation.
(4)² + (6)² = c²
16 + 36 = c²
52 = c²
√52 = c
