The shortest distance from A to B in the diagram is 17 m.

<h3>How to find the shortest distance?</h3>

The shortest distance from D to B can be found as follows:

using Pythagoras theorem,

c² = a² + b²

where

  • c is the hypotenuse
  • a and b are the other legs

Therefore,

DB² = 15² + 8²

DB² = 225 + 64

DB² = 289

DB = √289

DB = 17 m

Can someone please explain?
geniusboy [140]

This is an isosceles triangle. The angles at the base are congruent (they have the same measures).

Look at the picture.

We know: The sum of the measures of angles in a triangle is equal 180°.

Therefore we have the equation:

2x-10+2x-10+3x+25=180       <em>combine like terms</em>

(2x+2x+3x)+(-10-10+25)=180

7x+5=180           <em>subtract 5 from both sides</em>

7x=175              <em>divide both sides by 7</em>

x=25

m\angle A=2x-10\to m\angle A=2(25)-10=50-10=40\\\\m\angle C=m\angle A=40\\\\m\angle B=3x+25\to m\angle B=3(25)+25=75+25=100^o

<h3>Answer: D. m∠C = 40</h3>

X - the number

30\% x =42 \\&#10;\frac{30}{100}x=42 \\&#10;\frac{3}{10}x=42 \\&#10;x=42 \times \frac{10}{3} \\&#10;x=\frac{420}{3} \\&#10;x=140

42 is 30% of 140.
