Step-by-step explanation:
AC = 20
AB = 18
BC² = 20²+ 18² -2•20•18•cos(52°)
BC² = 280.72
BC = √280.72
BC ≈ 16.75
Angle C:
18² = 20² + 16.75² -2•20•16.75•cos(C)
324 = 400 + 280.72 -670•cos(C)
cos(C) = -356.72/-670
cos(C) ≈ 0.53
acos(0.53) = C
C = 57.8°
Angle B:
180-52-57.8 = 70.2°
Answer:
2
Step-by-step explanation:
y= 2x
How did i come to this conclusion??
-2 times something gives me -4
so I can use a variable to find it!!!
-4= -2x
-4/-2 =x
2=x
You would get the same answer for each value
Answer:
1047 m = c
Step-by-step explanation:
Given : Mr.kelly pays $12,564 a year for rent. His rent is a constant amount each month.
To Find:Which equation represents the amount he pays her month if m=months and c=total rent paid for the year?
Solution :
Since he pays for a year (12 months) = $12,564
Since His rent is a constant amount each month.
He pays for one month =
Thus the amount he pays per month $1047
If he pays for m months then the total amount(c) of rent for m months
⇒1047 m = c
Hence equation represents the amount he pays her month if m=months and c=total rent paid for the year: 1047 m = c
If Tommy can paint a fence in 7 hours, he paints 1/7 of a fence in 1 hour.
If Huck and Tommy get one fence done in an hour, Huck must be able to complete 1-(1/7)=6/7 of a fence in one hr.
6/7x=1
x=7/6
Final answer: 1 hour, 10 minutes
