Answer:
1) angle NMP=103 and angle LMP=77
2) angle QST=58 and angle RSQ=32
Step-by-step explanation:
1) can find the angle NMP:
180-(-20x+13)=(-16x+23)
180+20x-13=-16x+13
180-13-23=-16x-20x
144=-36x
x=-4
angle NMP: 180-(-16*(-4)+13) = 103
angle LMP: 180-103 = 77
============================================================
2) can find the angle QST:
90-(15x-43)=(8x+18)
90-15x+43=8x+18
90+43-18=8x+15x
115=23x
x=5
angle QST: 90-(15*5-43)=90-(75-43)=58
angle RSQ: 90-58=32
Hello,
A:
2x²-7x-4=0
==>2x²-8x+x-4=0
==>2x(x-4)+1(x-4)=0
==>(x-4)(2x+1)=0
==>(x=4) or (x=-1/2)
B: where is the sign "=" !!!!!!!!!!!!!!!!!!
81x^-1=(9x²+1)(3x+1)(3x-1) I can not go any further.
C)
2x²-32=0
==>x²-16=0
==>(x+4)(x-4)0
==>x=-4 or x=4
D:
where is the sign "="!!!!!!!!!!!!!!!!!!!!!!!!
x^2-7x+12=(x-4)(x-3) but I can not go ant further....
A) the standard of error would be that all the apartment costs would have a plus/minus of $80 so therefore the data received would be inaccurate.
The side opposite the 30o angle is 1/2 W. That is just a property of a 30 - 60 - 90 triangle. Use that fact to set up the pythagorean relationship.
w^2 = (1/2 w)^2 + (7 * sqrt(3)) ^2
w^2 = 1/4 w^2 + 49*3
w^2 = 1/4 w^2 + 147
3/4 w^2 = 147
w^2 = 147 * 4/3
w^2 = 49 * 4 = 196
w = sqrt (196)
w = 14
