Answer:
26 inches
Step-by-step explanation:
To find the area of a trapezoid, you must...
1) Add base 1 and base 2 together
7.5 + 5.5 = 13
2) Divide by 2
13 / 2 = 6.5
3) Multiply by height
6.5 x 4 = 26
Area = 26 inches
For (5, -2): -2 - 4(5) = -2 - 20 = -22 ≤ -5 [false]
For (-2, 1): 1 - 4(-2) = 1 + 8 = 9 ≥ -5 [true]
For (-4, 2): 2 - 4(-4) = 2 + 16 = 18 ≥ -5 [true]
For (1, -1): -1 - 4(1) = -1 - 4 = -5 ≥ -5 [true]
For (4, 0): 0 - 4(4) = 0 - 16 = -16 ≤ -5 [false]
Therefore, options B, C, and D satisfy the inequality.
Answer:
If these are ratios, then
2:7 = 6:21
Answer:
102.5
Step-by-step explanation:
Answer:
AC = 12.38 cm
Step-by-step explanation:
When there are 2 pairs given, we can use the sine rule to solve the problem.
By pairs we mean "an angle and side opposite to it"
<em>1 pair is 85.2 degree angle and 13 cm, and another pair is 71.6 degree angle and the side AC (which we want to figure out).</em>
<em />
Sine Rule is given by 
where,
A and B are the two respective angles and a and b are the two respective sides (of the pairs). Plugging all the info and using algebra, we have:

Thus, AC = 12.38 cm
