I'm assuming this is multiplication so it would be 14,400
Answer:
a
Step-by-step explanation:
The base angles PHJ and PJH are congruent , meaning ΔaPHJ is isosceles and so
HP = JP, thus
3x - 6 = x + 2 ( subtract x from both sides )
2x - 6 = 2 ( add 6 to both sides )
2x = 8 ( divide both sides by 2 )
x = 4
Hence
HP = 3x - 6 = (3 × 4) - 6 = 12 - 6 = 6 → a
Answer:
See explanation
Step-by-step explanation:
If 
then triangle PXY is isosceles triangle. Angles adjacent to the base XY of an isosceles triangle PXY are congruent, so
and
Angles 1 and 3 are supplementary, so
Angles 2 and 4 are supplementary, so
By substitution property,
Hence,
Consider triangles APX and BPY. In these triangles:
- given;
- given;- - proven,
so 
by ASA postulate.
Congruent triangles have congruent corresponding sides, then
Therefore, triangle APB is isosceles triangle (by definition).
