A conjecture and the two-column proof used to prove the conjecture are shown. Given: the measure of angle C B D equals 90 degrees. Prove: triangle A B C is a right triangle. Ray B D extends down and perpendicular from point B on segment B C. Drag an expression or phrase to each box to complete the proof. Statement Reason 1. m∠CBD=90° Given 2. ∠ABC and ∠CBD are supplementary. Response area 3. Response area Definition of supplementary 4. m∠ABC+90°=180° Response area 5. Response area Subtraction Property of Equality 6. ∠ABC is a right angle. Definition of right angle 7. △ABC is a right triangle. Definition of right triangle The option "Linear Pair Postulate" (3 of 4) has been grabbed. Press tab to choose where to drop it. Drop it by pressing the spacebar key. Cancel the operation by pressing escape.

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.

.there can be infinite values of m and n that can satisfy the above equation. for each value of m of m or n. there maybe infinite sets of solution for the above

step-by-step explanation:

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
