Which reason justifies the last step in a proof that ∆DEF ≅ ∆DAB?
lesya [120]
Hey there, Sheriawilright!

The correct answer should be C since we are given two sides AD is congruent to ED and D is the midpoint of Line BF meaning that BD and BF are the same. Also, it makes both lines make a vertical angle meaning they are the same. So we have two sides and an angle between, so the answer is Side Angle Side.

Find the equation of a line that passes through the point (2,1) and has a gradient of 2. Leave your answer in the form ax + by =
Arte-miy333 [17]

Step-by-step explanation:

normally, if we have the gradient (or slope of inclination or change rate) and a point, we start using the point-slope form :

y - y1 = a(x - x1)

with (x1, y1) being a point on the line, and a being the slope of gradient (or ... however you want to call it).

y - 1 = 2(x - 2) = 2x - 4

y + 3 = 2x

2x - y = 3

The first three terms of a sequence are given. Round to the nearest thousandth (if
Ksju [112]

Answer:

234

Step-by-step explanation:

The consecutive terms of the sequence have a common difference d

d = 17 - 10 = 24 - 17 = 7

This indicates the sequence is arithmetic with n th term

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 10 and d = 7 , thus

a_{33} = 10 + (32 × 7) = 10 + 224 = 234

Point A is the incenter of triangle DEF.
AleksandrR [38]

Answer: B, C, and E

Step-by-step explanation: I just took the Quiz. and since it’s the incenter that means the circle is inside the triangle so it passes through points X, Y, Z. it’s also answer choice C and E because they’re all congruent to each other so they’re all the same length XA and ZA and YA
