To Prove: ΔEFI ~ Δ GFH
Proof:
When two triangles are similar, their corresponding sides are Proportional and their corresponding interior angles are equal.
Two Triangles can be proven similar by following Similarity Criterion.
1. AA
2.SSS
3.SAS
→∠EFI=∠GFH-------[Vertically Opposite angles]
The Other statement which is needed to prove that triangles EFI and GFH are similar is
Option C:→ ∠E ≅ ∠G
So, Two triangles ΔEFI and Δ GFH are Similar by Angle-Angle(AA) Criterion.
To determine how much of the wall is blue we first need to find its area. The wall is a rectangle, then its area is the product of its height and length:

Hence, the area of the wall is 140 square ft. To determine how much of the wall is already painted we multiply this by 1/2, then:

Therefore, 70 square ft are blue.
The rate of change of any given function is simply taken to be the 1st derivate of that function.We are given:y = 5 x + 25So the rate of change is simply, rate of change = dy / dxdy = 5 dxdy / dx = 5
So rate of change = 5
Answer:
45350
Step-by-step explanation:
(8)(20)+(8)(6)(8)+20(8+6)(8)(20)+6
=160+(8)(6)(8)+20(8+6)(8)(20)+6
=160+(48)(8)+20(8+6)(8)(20)+6
=160+384+20(8+6)(8)(20)+6
=544+20(8+6)(8)(20)+6
=544+(20)(14)(8)(20)+6
=544+(280)(8)(20)+6
=544+(2240)(20)+6
=544+44800+6
=45344+6
=45350
Answer:
<em>T tof = 2 ( v 0 sin θ 0 ) g . T tof = 2 ( v 0 sin θ 0 ) g . This is the time of flight for a projectile both launched and impacting on a flat horizontal surface.</em>
