Which of the following statements are enough to prove that triangles EFI and GFH are similar?

SCORPION-xisa [38]

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.

For a science experiment Marcia dissolved 1.0 kilogram of salt in 3.0 liters of water. For a different experiment, Bobby dissolv

nekit [7.7K]

Marcia dissolved 1 kg of salt in 3 litres of water.
Bobby dissolves 2 pounds of salt in 7 pints of water
2.11 pints = 1 litre
7 pints = 7/2.11
= 3.32 litre
1 pound =0.45 kg
2 pound = o.45*2 kg
= 0.9 kg
So we find that Bobby is dissolving 0.9kg of salt in 3.32 litre of water
Marcia is dissolving 1 kg of salt in 3 litres of water.

a circle has a radius of 9 inches. In inches, what is the length of the arc intercepted by central angle of 3.25 radians

frutty [35]

Answer:

$\boxed {\boxed {\sf 29.25 \ inches}}$

Step-by-step explanation:

Since we are given the central angle in radians, we should use the following formula for the arc length.

$s= \theta r$

Where s is the arc length, θ is the angle in radians, and r is the radius.

We know this circle has a radius of 9 inches and the central angle is 3.25 radians.

θ= 3.25
r= 9 in

Substitute the values into the formula

$s= (3.25)( 9 \ in)$

Multiply.

$s= 29.25 \ in$

The arc length is 29.25 inches.

What is the first term in a geometric sequence if the common ratio is −2 and the sum of the first five terms is 77?

kirza4 [7]

Answer is a1 = 7

Using equation (derived from formula to find sum of values in a geometric series),
$77 \: = \frac{a(1 - ( { - 2}^{5}))}{1 - ( - 2)}$
Hence, solve for a.
