Hey there! I'm happy to help!
A <u>quadrilateral </u>is any polygon (enclosed shape) with four sides. Let's see what each of these shapes are.
- Scalene right triangle - the prefix <u>tri-</u><u> </u>means <u>three </u>(tricycle, tripod, triple, etc.<u>),</u> and all triangles have three sides, so this is not a quadrilateral.
- Obtuse scalene triangle - once again a triangle, so not a quadrilateral.
- Isosceles right triangle - would you look at that, another triangle! Not a quadrilateral.
- Hexagon - a hexagon is a six-sided polygon (<u>hex=six)</u>, so this is not a quadrilateral.
- Pentagon - a pentagon is a five-sided polygon (<u>pent=five, </u>like Pentatonix!). Not a quadrilateral
- Right trapezoid - a trapezoid is a quadrilateral with at least one pair of parallel sides!
- Venn diagram - a Venn diagram is a compare and contrast chart made of two overlapping circles (ZERO sides), so this is not a quadrilateral.
So, the only shape on your list that is a quadrilateral is 6. right trapezoid.
Have a wonderful day! :D
Answer:
134.4 centimeters
Step-by-step explanation:
This question is asking us for a missing leg on the triangle, lets call it x. Using the Pythagorean theorem (a²+b²=c²), we can figure out what value is missing (either a or b, they are interchangeable).
replace the values in the equation.
83²+x²=158²
get rid of the exponents.
6,889+ x² = 24,964.
subtract 6,889 from 24,964.
x²=18,075.
find the square root on both sides of the equation.
x=134.4432966.
I am assuming you want this rounded to the nearest tenth.
134.4 is your answer.

If the point is a y-intercept the x value would be zero. 8 is the slope, 7 is the y-intercept
y=mx+b

Answer:
Step-by-step explanation:
PX is 15 which is the radius
Find the circumference of the circle and subtract the length of the minor arc
Circumference of circle = 2 * pi * r = 2 * pi * 15 = 30 pi
length of arc = angle/360 * 2 * pi * r = 23/360 * 2 * pi * 15 = 1.92 pi
subtraction will give 30 pi - 1.92 pi = 28.08 pi
28.08 * 22/7 = 88.25 which is approximately 88
