5 x 7 = 35
I don’t know which one you need help with so I’ll answer #1. A triangle cannot have two right angles because the angles in a triangle have to add up to 180°. Since a right angle is 90°, two of those will make 180°. Since a triangle has three angles, that doesn’t leave anything for the third angle, and you can’t have a 0° angle. Also, you could have figured this out by trying to draw it, it’s impossible! This is because it would require a fourth line to complete the shape, which makes it a square!
Part A:
The HCF is an acronym for Highest Common Factor. An unknown number and 63 have an HCF equal to 9. The factors of 63 are 9 and 7. There are lots of numbers to which the HCF with 63 is 9. These should be divisible by 9 but not by 7. That being said, the answers could be 9, 18, 27, etc.
Part B:
LCM is the acronym for least common multiple. Given that the LCM of a number and 48 is 144, the other number could be determined by dividing 144 by 48. If we let x be the number,
x = 144/48
x = 3
