Greetings!

"Heather measured a swimming pool and made a scale drawing. In real life, the pool is 45 meters long. It is 65 millimeters long in the drawing. What scale did Heather use for the drawing?"...

65mm=45m
Reduce to Simpliest Form.
65/5=45/5
13mm=9m

As a Representative Fraction (scale), it would look like: (in regards to mm)
13:9000

Hope this helps.

Angle RZT=110 Angle RZS=3s Angle TZS=8s What are angles RZS and TZS?

nekit [7.7K]

Angles RZT, RZS, and TZS form triangle RZT, so they sum to 180. Thus, we have:

110+3s+8s=180

Simplifying, we have:

11s=70

Dividing by 11, we see that:

s=70/11

Therefore, RZS=3s=210/11, and TZS=8s=560/11.

What are the numerical measures of the angles?

vredina [299]

ANSWER

The sum of m∠DEA and m∠AEB is 180°.

Reason: The sum of angles on a straight line is always 180°.

$(x + 25)+(9x + 10)=180 \degree$

Group like terms to get,

$x+9x=180-25-10$

Simplify, and get,

$10x = 145$

Divide both sides by 10 to get,

$x = 14.5$

We substitute this value to get the required angles.

$m \: ∠DEA=x+25$

$m \: ∠DEA = 14.5 + 25 = 39.5 \degree$

$m\:∠AEB=9x+ 10$

$m\:∠AEB = 9(14.5) + 10$

$m\: ∠AEB=130.5 + 10 = 140.5 \degree$
