Angle DAC is 34 degrees
If a quadrilateral is a parallelogram, consecutive angles are supplementary
Angle ADC + Angle DCB = 180
Substitute the angle measure for ADC
125 + Angle DCB = 180
Subtract 125 from both sides
Angle DCB = 55
Since opposite angles of parallelograms are congruent we can write this equation
Angle CAB + Angle CAD = DCB
Now we substitute the known measures
21 + Angle CAD = 55
Subtract 21 from both sides
Angle CAD = 34
Therefore the measure of angle CAD is 34 degrees

Answer:
A 175/979 = M
Step-by-step explanation:
Si Matusalén vivió 979 años y Abraham vivió 175 esto quiere decir que abraham vivio menos años que Matusalén.
Por lo que la fracción va a tener que ser menor que 1 ya que al multiplicarla por la edad de Matusalén nos tiene que dar la de Abraham.
Tenemos que encontrar una fraccion que multiplicada por 979 nos de 175.
979 * X = 175
Tenemos que despejar la x y encontraremos el valor de la fraccion.
979 * X = 175
X = 175/979
Nos fijamos si se puede simplificar, no se puede asique este es el resultado final.
Answer:
Step-by-step explanation:
Supplementary angles- angles that equal 180
AOC is 44+56
AOC=100
EOB clearly is more than 100 degrees seeing as its wider than AOC so a is not true
Complementary angles- angles that equal 90
AOC is 100 degrees and BOC is 56
thats more than 90 so thats not true either.
Adjacent angles- angles with a common side and vertex and don't overlap. They do not need to have the same measure or add up to anything.
Both EOD and DOC share a vertex, O, and a side, OD, showing they are adjacent making the answer true.
The answer would be C. no, no, yes
Perpendicular lines have the slopes which product is - 1:
m 1 * m 2 = - 1
First we must transform the first line to the slope-intercept form:
x + 2 y = 4
2 y = - x + 4 /:2
y = - 1/2 x + 2
Therefore: m 1 = - 1/2
( - 1/2 ) * m 2 = - 1
m 2 = ( - 1 ) : ( - 1/2 ) = ( - 1 ) * ( - 2 ) = 2
m = 2 ( this is the slope that we need for our equation )
Then we will charge it to the formula : y = m x + b ( which also passes through the point ( 1. 5 ) ):
5 = 2 * 1 + b
5 = 2 + b
b = 5 - 2
b = 3
Answer:
y = 2 x + 3
I don’t know but I’ll try to figure it out
