15/2 = 7.5 Im sorry don't know about the integer form
Answer:
X=9 Angle= 55
Step-by-step explanation:
The sum of all the angles of a triangle is always 180
so we add the angles
50 + 75 + (5x + 10)=180
125 +5x+ 10=180
135 +5x = 180
5x= 45
x=9
to find the angle we substitute x for 9
5(9)+10=55
You know the triangle has a base of 6 meters, and that the formula to find the area of a triangle is 1/2bh or one-half of the base times the height. So, you would plug in 9 meters squared=one half of six times h, or 9m^2=1/2(6)*(h). In simplifying this, you would get 3h=9m^2. Divide both sides by three and get h=3. Hope this helps, and if you need any further explanations, please let me know!
So the solid consist of 1 pentagon, 5 congruent equilateral triangle and 5 congruent squares and has 11 vertices so the number of edges of this solid is 20. I hope you are satisfied with my answer and feel free to ask form more if you have more clarifications.
