MATH HELP! PLEASE! I need it ASAP. Thank you!?

Question

Question 1:
In acute triangle ABC, segment AD is an altitude, the measure of angle ADB = 4x2 + 26, BD = 9x - 3, and DC = 6x +8. Find BC. Show all work to recieve credit.

Question 2:
Triangle PQR is a 30-60-90 triangle with right angle Q and segment PQ as the longer leg. Find the possible coordinates of R if P(2,6) and Q(2,-6). Show all work to receive credit.

Please help me do these. They are the last two questions I have to answer. Only serious answers please. THANKYOU!

Answer 1

4x^2+26=90
4x^2=64
x^2=16
x=4

9x-3+6x+8=15x+5
15*4+5=65



PQ=12
QR=4 sqrt(3)
PR=sqrt(192)

(x-2)^2+(y-6)^2=192
(x-2)^2+(y+6)^2=48
y=-6
x=?
