My answer:
a.How are L and W, and d related?
Because L and W, and d are the 3 size of an right-triangle. So we use pytagon theorem to fill in the blank:
b. If L is 7 units long and W is 5 units long, how long is d
Once again, we use pytagon theorem to find out d
<=>
<=>
<=> d =
Hope it will find you well.
5a - 4a = -9 - 8a
a = -9 - 8a
9a = -9
a = -1
Answer:
-20√7
Step-by-step explanation:
Here. we want to write this in the simpler form
we can have 112 as; 16 * 7
√112 = √(16*7)
√112 = 4 √7
so, we have
-5 * 4 √(7 = -20 √7
A and 90-a is the measure of the two angles
a=90-a-6
2a=84
a=42
42° and 48°
Step-by-step explanation:
Step 1: Substitute 8 in the equation.
Step 2: Minus 8 from 15.
