So you need to use the inverse tan to find the measure of angle c.
So since tan is opposite over adjacent.
You get the inverse tan of 6/8. And you get 36.87 degrees.
X=7. if you need explanation message me
So first you would divide the 9 on both sides then 6 divided by 9 would be .6 repeating so m=.6 repeating.
Answer:
42cm²
Step-by-step explanation:
because if the perimeter of the rectangle is 28 then the length is 5, 5 - 11 = 6, the formula for finding the trapezium is to add the 2 parallel sides, half them, then times them with the length so your sum will look like this, 5+9=14, (i knew the other side was 9 as the length of AB is the same as the length of FC, which is the one of the parallel sides of the trapezium) then we do 14÷2=7, finally we times 7 by 6 which is 42cm²
7p - 4 + 12p = -3(5 + p)
7p - 4 + 12p = -15 - 3p
+ 4 + 4
7p + 12p = -11 - 3p
+ 3p + 3p
22p = -11
p = -1/2 Answer
