Answer:
-28 is the answer.
Step-by-step explanation:
84-56=28
56+28=84
-56+-28=-84
Answer
greater 30,15,5,-10 lessthan -30
Step-by-step explanation:
Multiply the length 7 tiles by the width of 2 tiles to get the area of 14 tiles
Nothing else is given, so for the two triangles to be congruent, the only possible proof is the ASA theorem.
first pairs of angles: 2x+7=x+21 => x=14
second pairs of angles: 8y-4=4y+28 =>y=8
The two triangles share the same side PR
Based on the Angle-Side-Angle Triangle Congruence theorem, these two triangles are congruent with x=14, y=8
(2x+7) +(8y-4) +Q=180 =>85
