HELP DUE IN 20 MINS!

m∠c =?? degrees

° m∠d =?? degrees

<c = 45°

<d = 90°

I am not sure okaythis ia sq right?

Step-by-step explanation:

This figure better be a square, otherwise there is no answer.

The diagonals of a square intersect at right angles, so d = 90 degrees. That property comes from the rhombus.

Squares have equal sides and the opposite sides are parallel. The triangle containing c is isosceles. The lower right corner is a right angle. So c must equal 45 degrees since the angle on the lower left must equal 45 degrees as well

Answer

c = 45

d = 90

answer: it's upside down and i can't read it

step-by-step explanation:

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
