Answer:
1 1/8
Step-by-step explanation:
x + 1 3/4 = 2 7/8 ( subtract 1 3/4 to isolate x)
2 7/8 is the same as 23/8
1 3/4 is the same as 7/4
you have to have the same denominator to subtract the fractions so you multiply 7/4 by 2
this gets 23/8 - 14/8 ( you subtract 23-14)
you get 9/8 which is the same as 1 1/8
Answer:
x = 7
Step-by-step explanation:
you can create a proportion:
PT / ST = PQ / RQ
36 / 30 = (5x+13) / (6x-2)
cross-multiply:
36(6x-2) = 30(5x+13)
distribute:
216x - 72 = 150x + 390
216x = 150x + 462
66x = 462
x = 7

If you have not already, convert the angle into a radius. xπ/180 where x is the angle in degrees.
The formula for area is A=r²Ф/2 where r is radius and Ф is angle in radians.
Solve to find the area.
Hope I helped :)
