Answer:
68
Step-by-step explanation:
Angle R is 124 which also makes angle FDE 124 because they are opposites which make them congruent. To find angle FDA you can make the equation 124 + ? = 180 then you subtract 124 from 180 to get 56 which is your FDA.
Since you know angle FDA and angle DAF are congruent you know that DAF is also 56. Then you multiply 56 by 2 (because 2 angles are 56) to get 112 and subtract that from 180 to get 68. That is your angle DFA
Answer:
where is the graph?
Step-by-step explanation:
Answer:
B. (3, 0), (0, -6)
Step-by-step explanation:
Plug 0 in for each variable one at a time, and you will get both intercepts.
First of all, triangles angles add up to 180 degrees.
BCD=120. To find BCA subtract 180-120 to get 60 degrees.
We know what ABC is, it equals 85, so far we have 2 angles.
Lets add them up, 85+60=145
Since the angles must add up to equal 180 we're going to subtract 180-145
Which equals 35, BAC=35 degrees.

Step-by-step explanation:
using the figure above and the fact that line / is parallel to segment AC, prove that the sum of the angle measurements in a triangle is 180. drag and drop the reason that align with the statement
