questions 3: ∆abc ~ ∆def. if ∠a=70° and ∠f=60°, what is the measure of ∠b? show all work.

The answer of 1 ques is x=12 units  and y=8 units.

The answer of 3 ques is  ∠B=50°

Step-by-step explanation:

Given the triangle JMN in which ΔJKL and ΔJMN are similar

therefore, we can write

⇒ and

⇒                                

⇒                                      

⇒

In next question of camps.

Part A: Given the two angles ∠ABC and ∠CDE are equal each 90°. As these are alternate angles and are equal hence, both lines AB and DE are parallel.

Part B: Additional angles of pairs ∠BAC and ∠CED, ∠ACB and ∠DCE are equal as first pair is of alternate angles and second pair is vertically opposite angle.

Part C: All the 3 angles of both triangles ΔACB and ΔECD are equal hence, by AAA similarity postulate or we can say by AA similarity postulate both triangles are similar.

Part D: Length of DE is

As the triangles are similar therefore their corresponding sides are proportional

Questions 3: ∆ABC ~ ∆DEF. If ∠A=70° and ∠F=60°, we have to find the measure of ∠B.

As, the triangles are similar corresponding angles are congruent ∴ ∠C=60°

By angle sum property of triangle

∠A+∠B+∠C=180°

⇒ 70°+∠B+60°=180°

⇒ ∠B=50°

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
