Answer:
82.5°
Step-by-step explanation:
This is the case of a isosceles triangle , as you may know in a isosceles triangle , there are two sides of equal length as well as two equal angles.
You know that the sum of angles in a triangle is 180°, therefore it comes to this equation :
15° + 2x = 180°
2x = 165°
x = 82.5°
therefore 82.5° is the correct answer.
Answer: Time spent on Question C=3 9/10
Step-by-step explanation:
Total Time to do the entire quiz= 20 minutes
Time spent on Question A=10 7 /10 minutes
Time spent on Question B=5 2/ 5 minutes
Time spent on Question C=Total Time to do the entire quiz-(Time spent on Question A+Time spent on Question B)
20mins- (10 7 /10 +5 2/ 5)
20mins - ( 15 7+4 /10)
20mins - ( 15 11/10=16 1/10))
20mins -16 1/10
19 10/10 -16 1/10
Therefore Time spent on Question C= 3 9/10
Answer:
1
Step-by-step explanation:
Let’s take a look at the definitions of all of these categories of polygon:
A rhombus is a quadrilateral with four equal-length sides
A trapezoid is a quadrilateral with at least one pair of parallel sides
A kite is a quadrilateral with two pairs of equal sides, where those sides are adjacent to each other
A quadrilateral is a four-sided polygon
And let’s compare our definitions with the figure:
- None of the sides of the figure are equal to each other, so we it can’t be a rhombus
- The slopes of all of the sides are different, so the figure can’t have a pair of parallel lines, ruling out the chance that it’s a trapezoid
- That first bullet point also rules out the possibility that our figure is a kite
- Our figure *is* a four-sided polygon though, so it meets the requirements for a quadrilateral
So, the only label that works for this figure is a *quadrilateral*.
