11. is 25°
(Both triangles have two congruent angles which means the 3rd angle is bound to be the same. Just add the 90° and the 65° to get 155 and subtract from 180° because all triangles equal 180°)
12. is 25°
(Same as before, two of the angles are congruent so the third one is the same. Add all of the angles together and have them equal 180° because their is a variable present. 2x+60+70=180 or 2x+130=180. subtract 130 from both sides to get the equation 2x=50 and then divide both sides by 2 to get x=25.)
13. y=14 and x=11.6 (assuming m<d says 15x ÷ 2 because I couldn't really read it)
(m<a = m<d and m<b = m<e because they are lined up together in the ABC and DEF equation. so 3y=42 and (15x÷2=87)
1834 bfc I believe that’s the right answer
Answer:
exact form - b = -11/5
decimal form - b = -2.2
Mixed number form - b = -2 1/5
Answer:
-1/63y^11
Step-by-step explanation:
because we multiply it
Answer: Hi! I would say it is D because the other answers really don’t make sense. And the passages said that they were rated low for air quality.
