Answer:
x = 127°
Step-by-step explanation:
in each triangle, the value of each exterior angle is equal to the sum of its two non-adjacent interior angles..
47° + 80° = 127°
or
the third angle in the triangle:
180° - (47° + 80°) = 53°
exterior angle:
180° - 53° = 127°
Answer:

Step-by-step explanation:
To solve this problem we need to write the mixed fraction as a fractional number, as follows:


Then, evaluating the expression:

= 
Answer:
67
Step-by-step explanation:
With the information of f(2) = 22-5, you can assume the equation will be f(x) = 11x-5. Using this, you can calculate f(5) by doing 11(5)-5, which is 50. 22-5 is 17, so 50+17=67
Answer: Look below :)
Step-by-step explanation:
7. <u>AD</u> and <u>CD</u> are congruent. Each of the triangles are the same in length and shape (both are right triangles). They are the same but are mirrored over the line <u>BD.</u>
8. I have no idea. Sorry.
Answer
-10
Step-by-step explanation:
-8w-7=9
add 7 to both sides
-8w=16
divide by negative 8 on both sides
w=-2
w-8=-10
