Which shape has two right angles and at least one obtuse angle? WILL GIVE BRAINLIEST ASAP:)
The trapezoid has two right angles and at least one obtuse angle, the correct option is B.
What is the obtuse angle?A obtuse angle is an angle which is greater than 90° and less than 180°.
A right trapezoid (also called right-angled trapezoid) has two adjacent right angles.
Right trapezoids are used in the trapezoidal rule for estimating areas under a curve.
An acute trapezoid has two adjacent acute angles on its longer base edge, while an obtuse trapezoid has one acute and one obtuse angle on each base.
Hence, the trapezoid has two right angles and at least one obtuse angle.

Out of 260 racers who started the marathon, 235 completed the race, 17 gave up, and 8 were disqualified. What percentage did not complete the marathon? Round your answer to the nearest tenth of a percent.
Answer:
9.6% or 9.7% did not finish
Step-by-step explanation:
You can solve this 2 different ways:
First way: 17+8=25, so 25 out of 260 did not complete. 25/260=0.096, or 9.6% did not finish.
Second way: 235 out of 260 finished. 235/260=0.903, or 90.3% finished. 100-90.3= 9.7, which is almost exactly equal to our first answer.
They can't be the same because 25/260 and 235/260 are very random decimals, so the answer is 9.6% to 9.7% :)

The perimeterof a squareis 20 feet.
What is the area of the square?
Answer:
C. 25 ft²
Step-by-step explanation:
the length of side = 20/4 = 5 ft
so the area of the square = 5² = 25 ft²
Answer:
C: 25 ft2
Step-by-step explanation:
Perimeter is the factor of all the side lengths added together. If 4 equal sides added together equals 20, what times 4 equals 20? 5 times 4 equals 20. Which means the side length is 5. Area is side length x side length, so 5 x 5=25 so the answer is C hope this helps!

The gardern is 12m by 10m. 15% of the total area is gardern patch and 3/8 is a flowerbed. The rest of the area is lawn. Pete sprays the lawn. The spray cost 0.35 per 3m2
Given :
The garden is 12m by 10m. 15% of the total area is gardern patch and 3/8 is a flowerbed.
Solution :
Area of lawn = Area of garden - area of garden patch - area of flowerbed.
[tex]A = 12\times 10 - 12\times 10 \times 0.15 - \dfrac{3}{8} \times 12 \times 10\\\\A = 57 \ m^2[/tex]
Total cost of spray is given by :
[tex]Total \ cost =Total\ area \times cost \ per \ area\\\\T = 57 \times \dfrac{0.35}{3} \\\\T = \$6.65[/tex]

x = 32
Step-by-step explanation:
The sum of all interior angles of this pentagon is 540
Solve for x by using this formula
540 = (180-71)+(180-85)+(180-44)+(180-3x)+(180-2x)
540 = 700 - 5x
540 - 700 = -5x
-160 = -5x
-160/-5 = x

hope this helps
have a good day :)
Step-by-step explanation:
Answer:
a = [tex]\frac{4}{3}[/tex]
Step-by-step explanation:
To solve for a, you must isolate it (variables on one side, constants on the other):
8 = 3a + 4 (starting equation)
8 - 4 = 3a + 4 - 4 (subtract 4 from both sides)
4 = 3a + 0 (calculate)
4 = 3a (no need to write +0)
[tex]\frac{4}{3}[/tex] = [tex]\frac{3a}{3}[/tex] (divide both sides by 3)
[tex]\frac{4}{3}[/tex] = a (simplify -- 3/3 = 1)
So, a = [tex]\frac{4}{3}[/tex].

¿ cuál será el volumen de una pirámide hexagonal si las aristas de la base miden 8cm, la apotema vale9.93cm y su altura es de 28cm?
Answer:
2224.32 cm³
Step-by-step explanation:
La fórmula para el volumen de una pirámide hexagonal = 1/3 (1/2 × P × a) × h
Donde a = Apotema = 9,93 cm
P = Perímetro =
Pirámide hexagonal = 6 × Bordes de la base = 6 × 8 cm = 48 cm
h = Altura = 28 cm
Por eso,
Volumen de la pirámide hexagonal = 1/3 (1/2 (48 × 9.93) × 28 cm
= 1/3 × 238.32 × 28 cm
= 2224.32 cm³
Volumen de la pirámide hexagonal = 2224.32 cm³
