Answer:

∠ACD= 109°

Step-by-step explanation:

∠A=38

180- ∠A= ∠B+C

180-38= 2∠B( ∠B=∠C) ( angles opposite to equal sides are equal)

142=2∠B

∠B=71

∠ACD=∠A+∠B ( exterior angle property)

∠ACD= 38+ 71= 109°

21) Write the equation for the line through two given points.<br> Passing through (0, -1) and (2, 3)

Viefleur [7K]

Answer:

Point Slope: (y + 1) = 2x

Slope Intercept: y = 2x - 1

Step-by-step explanation:

I'll do it in two forms.

Slope = (3 + 1) / (2 - 0) = 2

Point - Slope: (y + 1) = 2x

Slope Intercept: y = 2x + b

-1 = b

y = 2x - 1

Answer:

<u>93.1 millimeters</u> is the size of the ant in the photo.

Step-by-step explanation:

Given:

A photo of an ant in a science book is increased 565% as large as the actual size.

If the ant is 14 millimeters.

Now, to find the size of the ant in the photo.

The actual size of ant = 14 millimeters.

The size of the ant in the photo is increased 565% of 14 millimeters.

Now, to get the size of the ant in the photo we put an expression:

According to question:

$14+565\%\ of\ 14\\\\=14+\frac{565}{100}\times 14\\\\=14+5.65\times 14\\\\=14+79.1\\\\=93.1\ millimeters.$

Therefore, 93.1 millimeters is the size of the ant in the photo.
