Answer:
1/3 x + 1/2
Step-by-step explanation:
combine like terms the two opposites cancel out 2/3 and -2/3
1/3x + 3/4 -1/4 3/4 -14 = 12
13x + 1/2 (answer)
130+45= 175
she took out $175
I divided the figure into two rectangles, found their areas separately and added them up to get the final area 168 cm squared.
A. 25+90=115, 180-115=65 (III) b. 65+90=155, 180-155=25 (I) c. 180-25=155 (V)
Answer:
Let ΔABC and ΔDEF be two triangles such that ∠A = ∠D and ∠B = ∠E.
∠A + ∠B + ∠C = 180 0 (Sum of all angles in a Δ is 180)
∠D + ∠E + ∠F = 180 0 (Sum of all angles in a Δ is 180)
⇒ ∠A + ∠B + ∠C = ∠D + ∠E + ∠F
⇒ ∠D + ∠E + ∠C = ∠D + ∠E + ∠F (since ∠A = ∠D and ∠B = ∠E)
⇒ ∠C = ∠F
Thus the two triangles are equiangular and hence they are similar by AA.
