1x + 4y = 11 ⇒ 5x + 20y = 55
5x - 7y = -10 ⇒ <u>5x - 7y = -10</u>
<u>27y</u> = <u>65</u>
27 27
y = 2¹¹/₂₇
x + 4(2¹¹/₂₇) = 11
x + 8²²/₂₇ = 11
<u> - 8²²/₂₇ - 8²²/₂₇
</u> x = 2⁵/₂₇
(x, y) = (2⁵/₂₇, 2¹¹/₂₇)
You need to know more information, not just the length of the hypotenuse.
If you know the length of one leg use Pythagoras theorem to find the other.
If you know the value of one other angle use trigononemtry
The correct answer is D.
X=7
8=7+1
8=8
Answer:
1 square meter = 10000 square centimeters.
Step-by-step explanation:
We know that 1 meter = 100 centimeters.
Then 1 square meter = ( 100 cm)(100 cm) = 10000 square centimeters.
Then:
1 square meter = 10000 square centimeters.
