Use the Pythagorean theorem:
We have:
Substitute and solve for x:
Answer: x=14.4
Step-by-step explanation:2.5x=48-12
2.5x=36
x=14.4
Answer:
a= 4.993
c = 5.824
A= 59°
C = 90°
Step-by-step explanation:
b=3, B=31°
Since it's a right angle.
C = 90°
A = 180-90-31
A= 59°
For side a and c
a/sin A = b /sin B
a = sinA * b/sin B
a= sin 59 * 3/sin31
a= 4.993
a = 5
c/sin C = b/sin B
c = sin C * b/sin B
c = sin90 * 3/sin 31
c = 1* 5.824
c = 5.824
154.35 - 10.37 = 143.98
143.98 - 27.83 = 116.15
10.37 = 116.15x
x = 0.0893
Change x to percent form to get 8.93% tax rate.
Answer:
B
Step-by-step explanation:
-3x+3y=-18 ➡3y=3x-18 ➡y=x-6
5x-2y=9➡-2y=-5x+9➡y=2.5x-4.5
2.5x-4.5=x-6
1.5x=-1.5
x=-1
y=-1-6
y=-7
