Answer: hypotenuse and leg of one right triangle
Step-by-step explanation:
The HL Postulate states that if the hypotenuse and leg of one right triangle are congruent to the hypotenuse and leg of another right triangle, then the two triangles are congruent.
Answer:
12.68°
Step-by-step explanation:
We know all three sides (18, 80, 82), but we only need two: 18, and 82. Why? What we do here is find the arcsin of the first leg divided by the hypotenuse.
arcsin(18/82)
<em>18/82 is the same as 9/41, which equals 0.21951 repeating (all 5 digits after the decimal are repeating, by the way).</em>
arcsin(0.21951)
<em>What you see above this statement equals 0.22131 radians.</em>
0.22131 rad
<em>To convert this to degrees, multiply by 57.2957795.</em>
0.22131 * 57.2957795
<em>0.22131 times 57.2957795 is 12.680128961145.</em>
12.680128961145°
<em>The directions say the final answer has to be two decimal places. So this becomes 12.68 (0 is less than 5, so round down).</em>
12.68°
Angle A is 12.68°.
Answer:
115.909091
Step-by-step explanation:
To find this, we have to find a value x such that 2*10^9 * x = 4*10^6. This is so that if we find x, 2*10^9 is x times smaller than 4*10^6. Then, using the multiplicative property of equality, we can divide both sides by 2*10^9 (to separate x) to get 4*10^6/2*10^9=x. Since 4/2=2 and 10^6/10^9=1/10^3 (since for every power of 10, we add 1, so we have 10*10*10*10*10*10/(10^6)*(10^3) and the 10^6’s therefore cross out), our answer is 2/10^3=2/1,000. However, this is clearly not the answer we’re looking for, and even if we find out how many times larger 2*10^9 is than 4*10^6 by switching the denominator and numerator, we end up with 500. Thus, you must have entered something wrong.

Answer:
(-9,-10)
Step-by-step explanation:
The x is already to you for the ordered pair. Step 1: Substitute the X. -9(-9)+10y=-19 then 81+10y=-19, subtract 81 from both sides, 10y=-100, divide both sides by 10. Finally, y=-10
