Answer:
They're both acute
Step-by-step explanation:
They both meausre less than 90°
A right angle would look like an L (it could be a flip L as well)
And an obtuse angle is anything bigger than a right angle
Answer:
2/5.
Step-by-step explanation:
The prime numbers from 1 to 20 are 2, 3, 5, 7, 11, 13, 17 and 19.
A total of 8.
So the probability of rolling a prime number is 8/20
= 2/5.
Answer:
Add 4 positive unit tiles to each side.
Step-by-step explanation:
The original equation is:
3x - 4 = 2x + 5
After adding 4 positive unit tiles to each side, we get:
3x - 4 + 4 = 2x + 5 + 4
3x = 2x + 9
which simplifies the original equation, because at the beginning there were independent terms at both sides of the equal sign and now all independent terms are on the right side (the +9 term). Notice that the other options don't give this result.
Answer:
altitude = 30 cm
lateral surface area = 301 cm² (approximately)
Step-by-step explanation:
let the altitude be x,
240=6*4*x/3
or, x=30 cm
Lateral surface area,
=l×√(w/2)²+h²]+w×√[(l/2)²+h²]
=6×√[(4/2)²+30²]+4×√[(6/2)²+30²]
≈300.99806
≈ 301 cm²
