Answer:
A: Angle J
Step-by-step explanation
If the two triangles are congruent then their corresponding angles are also congruent. This means that angle P is congruent to angle J, angle Q is congruent to angle K and angle R is congruent to angle L. Hope this helps :D
Divide the polygon into separate shapes. Like a rectangle and then a triangle.
find the areas of those shapes and then add them together.
A= l x b
70 = 14b
divide both sides by 14
b= 5
the answer is B
because 54x 3= 162 x3 = 486x3= 1458x3=4,374x3=13,122x3=39,366x3=118,098x3=354,294
