All of these questions confuse me, i really don’t know how to do them can someone please explain and possibly solve the answers with me? i need it for tomorrow and i might be going to bed soon :(

- Do not ping the Moderators, unless someone is breaking the rules.
- Do not ping the Helper Moderators, unless there is a conflict between helpers.
- Do not ping other members randomly for help.
- Ask your question and show the work you've done so far. If you've posted a screenshot of a question, specify which part you need help with.
- Wait patiently for a helper to come along.
- If the Helper has answered your question, remember to thank them with the Mathematics Ranks bot and close the thread with:

Feel free to nominate the person for helper of the week in #helper-nominations
If you're happy with the help you got here, and the server overall, you can contribute financially as well:

For the triangles in the first picture, take note of what sides are known with respect to the angle. And recall the definitions of trigonometric ratios:
sin(x) = (opposite side)/(hypotenuse)
cos(x) = (adjacent side)/(hypotenuse)
tan(x) = sin(x)/cos(x) = (opposite side)/(adjacent side)
Ah, ok.
In the second picture:
- Recall that the height dropped onto the base of an isosceles triangle is also a median.
- Find one of the angles of the triangle ADC, for example, and then see how you can get to the needed angle.
- Note that the needed angle is the different of angles BAD and BAC.

would this be a correct way of solving tge problem with an isosceles triangle with a side of 14 and a bottom side of 10 as a whole? I have found that 10 / 2 is 5, and since both of the sides are the same, i wrote 14 on one and pretended the other 14 was there. I then marked the unknown angle (x) and marked the right angle from the dotted line to find the hypotenuse. I then entered cos ^-1 ( 5 over 14 ) and got 69.07516757 which rounds up to 69 as the nearest whole number

Well, arccos(5/14) is approximately 69° (don't forget the degrees sign, by the way). Also, that's rounding down (or just rounding), not rounding up.
The approach is correct.

wait so in a more simply put way, how could i answer this question? i’m so tired my brain is boiled 😢

Do you know what vertical and supplementary angles are?
