Answer:
It will be 120°
It because if you matched those two points you will have two angles of 90° degree inside that square and in the triangle at the above 120-90= 30 degrees for both angles and since that all angles of the triangle are equal 180 then 180-(30+30)=120°.
Sorry if my explanation isn't that good.
Answer:
(7b-8) (7b+8)
Step-by-step explanation:
49b^2 – 64
This is the difference of squares
(a^2 -c^2) = (a-c) (a+c)
a^2 = 49b^2 so a = 7b
c^2 = 64 so c = 8
(49b^2 -64) = (7b-8) (7b+8)
You do 150/6 = 500/x
150x = 3000
Means x = 20
