Answer:
90° and 61°
Step-by-step explanation:
Since it's a right angled triangle, I thought it was wrong since you said right angle.
180 - 29 = 151
There is always one right angle in a right angled triangle, which is 90°, so you just have to deduct 90° and 29° from 180° and you will find out the answer.
180 - 29 - 90 = 61°
We are given :
The cost of one adult ticket = a.
The cost of one child ticket = c.
<u>Roy buys</u>
6 adult tickets and 2 child tickets.
Total amount = $66.
Therefore, first equation for Roy total amount would be
<em>6a +2c = 66 --------------------(1)</em>
<u>Elisa buys</u>
5 adult tickets and 4 child tickets.
Total amount = $62.
Therefore, second equation for Elisa total amount would be
<em>5a +4c = 62 --------------------(1).</em>
Therefore,
<h3>Roy
<u>6</u>a + <u>2</u>c = <u>66</u></h3><h3>
Elisa <u>5</u>a + <u>4</u>c = <u>62.</u></h3>
The final would be
6X+9Y+14
How?
You combine similar numbers. You can't combine 5X with 2 but you can combine 5X with X
also just the letter X means it is a one.
