By definition we have to:
Acute triangle - It is a triangle that has all acute angles. An acute angle is one whose degree of measurement is less than 90.
Therefore, Charlene's definition is correct.
Charlene said:
triangle is a triangle whose three interior angles have measures less than 90 °
Answer:
C.Yes, because this definition fits all acute triangles and does not fit triangles that are not acute.
Answer:
144cm^3
Step-by-step explanation:
1) split the figure so you can find the volume of two rectangular prisms.
2) Find the volume of the first rectangular prism with the measurements of 2, 5, and 8. So the volume is 80
3) Find the volume of the second rectangular prism with the measurements of 4, 2, and 8. So you have 64
4) Add the two values 80+64.
5) Then that's your answer; 144
Hope this helps! :D
Answer:
RT = 12 units
Step-by-step explanation:
From the figure attached,
ΔSRQ is right triangle.
m∠R = 90°
An altitude has been constructed from point T to side SQ.
m∠RTQ = 90°
By applying geometric mean theorem in triangle SRQ,
x² = 16 × 9
x² = 144
x = √144
x = 12
Therefore, length of altitude RT is 12 units.
Answer:
25 in^2 or inches squared
Step-by-step explanation:
5 in * 5 in = 25 in^2 (inches squared)
Step-by-step explanation:
Given that,
Mass of Ella is 56 kg and mass of Tyrone is 68 kg.
Position of Ella is 1.5 m on the ramp.
Potential energy of an object is given by :
P = mgh
It is directly proportional to the position of an object.
If Tyrone stands at the top of ramp at more height than Ella, it will have more potential energy. Hence, the correct option is (d) "If Tyrone stands at the top of a 2 m high ramp, his potential energy will be greater than Ella's."
