The first one is the answer to the question
Recall that, an absolute value expression is a piece-wise in effect, thus we'd check the single-sided limits,
Answer:
SAS Similarity
Step-by-step explanation:
ΔOPQ similar to ΔRST
∠Q = ∠T
OQ : RT = 28 : 84 = 1 : 3
QP : TS = 16 : 48 = 1 : 3
The measures of two sides of ΔOPQ are proportional to the measure of two side of ΔRST and their included angles are congruent. The triangles are similar by SAS Similarity.
Answer:
it is in quadratic equation meaning you use Plus or minus
