Step-by-step explanation:
I'm sorry if my terminology isn't correct because I've learnt it slightly differently, but what I'm assuming is this:
For A, you can rewrite the integers as 28-15+22 as a + and a - next to each other result in a subtraction.
For B, you simply do 15+22 is 37 and 28-37 is -9 due to BIDMAS (or PEDMAS if you're American).
Answer:
An angle only has one bisector. Each point of an angle bisector is equidistant from the sides of the angle. The interior or internal bisector of an angle is the line, half-line, or line segment that divides an angle of less than 180° into two equal angles.
Step-by-step explanation:
7 because 4+2=6 and 1/2+1/2=1 so 6+1=7
Step-by-step explanation:
check the tile whose side length is divisible by both 150 and180 in such a way that you don't get decimal points
150÷4=37.5 so that is impossible
150÷8=18.75 so that is also impossible
150÷6=25 180÷6=30
so the six sided tile is applicable
Obtuse, because the triangle has an angle greater than 90 degrees.
