Answer:
a)45º
b)22º
c)22º
Step-by-step explanation:
Add Angle b and angle a (45+113) then subtract from 180º (because that is the total of all triangle angles) and you get 22º
9514 1404 393
Explanation:
If the amount of change due to rounding is the same for both numbers, the original difference and the difference of rounded values will be the same. This will always be the case if the hundredths digits are the same to start with.
<u>Example</u>:
A = 0.56 ⇒ C = 0.6
B = 0.66 ⇒ D = 0.7
__
B - A = 0.66 -0.56 = 0.10
D - C = 0.7 -0.6 = 0.10 . . . . . same as B - A, ∴ Dominic is incorrect.
The factor pairs of 100 are 1 and 100, 2 and 50, 4 and 25, 5 and 20, and 10 and 10. As such, you can only have 5 rectangles with different side lengths assuming all side lengths are integers.
Answer:
-1/5 and -1
Step-by-step explanation:
x=0 y=-1 so y-intercept is -1
y=0 x=-1/5 so x-intercept is -1/5
There solutions are equal.
