But i think

Complemantary are angles whose sum is 90 and supplementary are the ones whose sum is 180

So
Complementary of 60 is 30
And
Supplementary is 120

Pleasee tell where i m wrong but this is what i studied and i am sure its correct

Answer: The correct answer would C. Complement 70. supplement 160.

Step-by-step explanation:

  • 60+B+B=90
  • 60–60+B+B=90–60
  • B+B=30
  • 2B=30
  • 2÷2B=30÷2
  • B=15

Therefore, since A=B+60 then  A=15+60 which equals 70 . SO the answer would C.

* Hopefully this helps:) Mark me the brainliest:)!!!!

A certain quadrilateral has two pairs of parallel sides. The opposite sides are equal in length. There are also 4 right angles.
DENIUS [597]

Answer:

12 + 12 = 24

Step-by-step explanation:

P = 2L + 2W

P = 2*16 + 2W

P = 56

56 = 32 + 2W     Subtract 32 from both sides

56 - 32 = 2W

24 = 2W              Divide by 2

24/2 = 2W/2

12 = W

The answer you want is 2 * 12 = 24

How many solutions does the linear equation have?
riadik2000 [5.3K]

Answer:

infinite solutions

Step-by-step explanation:

Given

x + 3 + 2x = 4 + 3x - 1 ( simplify both sides )

3x + 3 = 3x + 3

Since the equation is the same on both sides.

This indications the equation has an infinite number of solutions

Can someone explain to me how to find the missing terms and common ratio of question #7, and how to answer #8 please
NeTakaya
7. general term of gp is given by ar^n-1
hence,4th term is given by

ar^3=15 ------(1)
ar^6=405-----(2)

equation 2/1,we get
r^3=27
so common ratio r=3
putting value of r in equation 1,
we get a=5/9

so gp upto 7 terms will be 5/9,5/3,5,15,45,135,405

8. a=3
given 4th term is -24
so ar^3=-24

substituting value of a we get r^3=-8
r^3= -2^3
so r = -2

using this x2 is ar= 3*-2=-6
           
               x3 is ar^2= 3*4=12

Number 12.
const2013 [10]

D

given the 2 equations

x + 2y = - 8 → (1)

- 4x + y = 5 → (2)

multiply (1) by 4

4x + 8y = - 32 → (3)

add (2) and (3) term by term to eliminate term in x

9y = - 27 ( divide both sides by 9 )

y = - 3

substitute y = - 3 in either (1) or (2) and solve for x

(1) : x - 6 = - 8 ( add 6 to both sides )

x = - 2

solution is (- 2, - 3 ) → D
