The sum of the angles in any triangle is 180 degrees. If one of the three angles is 90 degrees (a right angle) the the sum of the other two angles is 90 degrees. Therefore each of the other two angles must be acute.
The statement is TRUE.
I believe the correct answer is D Aarron Burr
Answer:
40πcm
Step-by-step explanation:
circ = 2πr
if d = 40cm
r = 20cm
∴ c = 2×π×20
= 40πcm
= 125.66cm
Answer:
10 cm
Step-by-step explanation:
The area (A) of a rhombus is calculated as
A = × d₁ × d₂ ( d₁ and d₂ are the diagonals )
Here A = 60, d₁ = 12, thus
60 = 0.5 × 12 × d₂ = 6 d₂ ( divide both sides by 6 )
d₂ = 10
The other diagonal is 10 cm
15
The volume of the cube is 15 hence it will take up 15 cubic units.
