Answer:

A"B" = \frac{AB}{2}

Step-by-step explanation:

Given

k = \frac{1}{2} --- scale factor

Required

Relationship between AB and A"B"

k = \frac{1}{2} implies that the sides of A"B"C" are smaller than ABC

i.e.

A"B" = k * AB

A"B" = \frac{1}{2} * AB

This gives:

A"B" = \frac{AB}{2}

Fed [463]

Answer:

(x + 7) (x + 7)

Step-by-step explanation:

What's the square root of x^2?

That's x

What's the square root of 49

That's 7

And what makes 14?

7 + 7 = 14

So therefore the answer is (x + 7) (x + 7)

Find angle x and y. Please show step by step process.
lora16 [44]

Answer:

x = 60, y = 25

Step-by-step explanation:

Δ ABC has 3 congruent sides and is equiangular, thus

the 3 angles are congruent, all 60°

x = 60

∠ ABC and ∠ CBD are adjacent and supplementary, sum to 180° , then

∠ CBD = 180° - 60° = 120°, so

y = 180 - (120 + 35) = 180 - 155 ← sum of angles in triangle

y = 25
