Answer:
the answer is A
Step-by-step explanation:
Step-by-step explanation:
x² = 50²+ 55² - 2 • 50 • 55 • cos61°
Since AS is a height issued from A and the perpendicular bisector of [MP] at the same time (given), so the triangle AMP is an isosceles triangle of vertex A. Then, AM=AP
MS=SP ( AS bisects MP as stated in the given )
AS is a common side between triangles ASM and ASP
Therefore, triangles ASM and ASP are congruent (SSS)
Ok. Could I have a picture of the question? :)
