Answer:
Step-by-step explanation:
This triangle is a 30°-60°-90° triangle, so you should always remember the rule shown in the picture. Because y is across from the 60° angle, it will be 
. 3 is x because it is across from the 30° angle, so y will be .
Pls only answer if you know it:) The numbers are 19, 36, 24, 40, 17, 43, 30, 31, 37, 28, 45, 32, 16. What are the first quartile

Step-by-step explanation:
The reason being that I just did it myself on a lesson and got it right.
Answer:
It should be 60 degrees
correct me if wrong but since it's supplementary, you subtract 155 - 35 then from 180 and you get 60
Im not 100% about this tho but like 75% sure
Answer:
A: 180° B: 360° C: 540°
Step-by-step explanation:
A: The measures of interior angles of a triangle sum to 180°. Since figure ABC is a triangle, the interior angles of figure ABC sum to 180°.
B: We can see the quadrilateral ACDE is a trapezoid. If you can see, the trapezoid can be split into two triangles if you connect points C and E. As U mentioned before, the measures of interior angles of a triangle sum to 180°. Since we know figure ACDE can be split into <u>two triangles</u> we have to do: 180x2 which is 360°.
C: Now that we know the Pentagon ABCDE can be split into 3 triangles(1 from figure ABC and 2 from figure ACDE), we have to multiply 180 by 3 because like I mentioned before, the measures of interior angles of a triangle sum to 180°. So, 180x3=540°.
