In the accompanying diagram of ABC ca is extended to D, m∠ABC = 70 and m∠BCA =50 Find m∠DAB
zvonat [6]

Answer:

<em>120 degrees</em>

Step-by-step explanation:

Find the diagram attached.

From the diagram;

Interior angles are m∠BCA and m∠ABC

Exterior angle is m∠DAB

The sum of interior angle of the triangle is equal to exterior

m∠BCA +m∠ABC =m∠DAB

Given

m∠ABC = 70

m∠BCA =50

m∠DAB = 70 + 50

m∠DAB = 120 degrees

<em>Hence the measure of m∠DAB is 120 degrees</em>

GEOMETRY. PLEASE HELP ASAP!! I AM STUMPED! O.o
vagabundo [1.1K]

The point R has coordinates (-5,-5) and the image point R' has coordinates (2,-7).

If

  • -5+a=2, then a=2-(-5)=2+5=7;
  • -5+b=-7, then b=-7-(-5)=-7+5=-2.

Thus, the translation rule is

(x,y)→(x+7,y-2)

or T_{(7,-2)}(RSTU)

If point U has coordinates (-5,1), then its image U' has coordinates (-5+7,1-2) that is (2,-1).

Answer: correct choice is B

3x+2+x+8=180; 4x+10=180; 4x=170; x= 170/4= 42.5

Angle on top is x+8=42.5+8=50.8

Angle on the bottom is 3x+2=3•42.5+2= 129.5
