Find the m∠cde, if m∠bac = 55° and ∠bca is a right angle. 35° 45° 55° 90°

Step-by-step explanation:

We have been given an image of two triangles.

Since segment AB is parallel to segment CD and segment BC is parallel to segment DE.

We can see that segment AE is transversal for our given triangles.

Since corresponding angles of two parallel formed by a transversal are always equal.

We can see that corresponds to angle .      

Let us find measure of angle ABC using angle sum property.

Therefore, measure of angle CDE is 35 degrees.

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
