8m - 5
When collecting like terms you are adding or subtracting 2 "things" that have the same variable (letter).
-99..?? I think that’s the answer
<BAC = <DEC = 30°
<BCA = <DCE = 70°
<CDE (or m<D) = 180° - <DEC - <DCE
<CDE = 180° - 30° - 70°
<CDE = 80°
The number that belongs in the green box is 80
The answer to your math question is 66°.
Adding 47° and 67° is 114°.
Subtracting 114° from 180° equals 66°.
Answer:
- D. No, they are not similar.
Step-by-step explanation:
<u>Check the ratio of the two given sides:</u>
- MV/VT = 21/49 = 3/7
- LV/VU = 8/28 = 2/7
Ratios are different so the triangles are not similar
Correct choice is D
