Well in area you multiply and perimeter you add, so right now you are multiplying the measures of the triangle, So you can either write out the problem and solve it or use a calculator to get you answer, but I would say to solve it because you never if the calculator could be wrong, so if you wanna write it out then you write 9 then put the 14 under it and put the 5 under 14 but under the 4 of 14, so basically you are just going to multiply 9 by 14 to get 126 then multiply 126 by 5 to get 630, so now 630 is your final answer

ok so lets start of with the fact that the whole thing is 21 units.

So we do 21-9=12 so then we now know that the rectangle is 12 so then we do 12*8 units which is= 96 . Now the triangles. so the first one we know that its 8*3 and times it by 1/2 because two triangles is equal to a rectangle so the first triangle is 12 and now the second. its 9-3= 6 then its 6*8*1/2 which is equal to 24 so now the final answer is

96+12+24 which is equal to 132 so i'm guessing it 132 square units

The first five terms of an arithmetic sequence are shown below: 20, 17, 14, 11, 8, . . . Let n represent the term number and f(n

Leona [35]

Answer: 17 -3n

Explanation:

In the given arithmetic progression 20,17,14,11,8....

first term that is a = 20

common difference that is d= a2-a1 = 17-20 = -3

let n is the nth term

$a_{n}$ = a+(n-1)d

substituting the values of first, common,difference and n

$a_{n}$ =20+(n-1) (-3)

= 20 -3n+3

=23 -3n

In the figure, m∠B = m∠C and ∠D is a right angle. cos B =

Rasek [7]

Answer: The correct option is (a), i.e., cos B= sin A.

Explanation:

It is given that the ∠B = ∠C and ∠D is a right angle.

Since two corresponding angles of both triangles are same, so by angel sum property three angles are also equal. Therefore by AAA rule both triangles are similar.

It is given that,

$\angle B=\angle C$
