Answer:
The answer is 11.1 sq hope it helps and good luck!
Step-by-step explanation:
Answer:
See below
Step-by-step explanation:
When you have 2 sides and the angle between them you use the cosine theorem or law of cosines:


After you have a side and the opposed angle (side b and angle B), you use the law of sines:

I will calculate angle A first:

Same for angle C:

The sum of the angles is 36° + 61.2° + 25.3° = 122.5°; The sum must be 180° so this isnt a triangle.
I re did the problem using B as 63° instead of 36° in case you wrote it wrong and I got a satisfactory answer.
using B = 36:
b = 36.6
angle A = 86.4°
angle C = 29.1°
A+B+C = 86.4° + 29.1° + 63° = 178.5° ~ 180°
Answer:
EF = 7 units
AD = 3 units
BC = 11 units
Step-by-step explanation:
Since it is an isosceles trapezoid and the midsegment is x, the sum of the bases divided by 1/2 is the value of the midsegment, x.
x = 1/2(x-4 + 2x-3)
x = 1/2x - 2 + x - 1 1/2
x = 1 1/2 x - 3.5
-1/2 x = -3.5
x = 7 units
EF = 7 units
AD = 7-4 = 3 units
BC = 2(7) - 3 = 11 units
Answer:
12
Step-by-step explanation:
Just add 4 more to 8 and you get 12
2(P+1)+3(P+2)>2
Distribute
2P+2+3P+6>2
Simplify
5P+8>2
Subtract 8 from both sides
5P>-6
Divide both sides by five
P>(-6/5)
Turn to mixed number and you're done.
P>-1 and 1/5
