Answer:
364.8 ft^2.
Step-by-step explanation:
I assume you want the area of the figure.
Total area = area of the top triangle + area of the trapezium
= 1/2 * base * height + 1/2 * height * ( sum of the parallel sides)
= 1/2 * 18 * 6 + (14/2)( 18 + 26.4)
= 54 + 310.8
= 364.8 ft^2.
12 ÷ 3 - 5(12) + 4(12 - 2)
= 4 - 60 + 4(10)
= -56 +40
= -16
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)
Answer:
(-3,2)
Step-by-step explanation:
when reflecting over the y axis all you have to do is flip the signs on the x values so it would be (-3,2)
What’s standard form again? I forgot
