Answer: length of DE is about 3.3 ft
Step-by-step explanation: A calculator is necessary!
DE is the unknown hypotenuse of the triangle
get the sine of 23° = 0.3907311285
Use the equation for sine
<em>sin = o/h</em> .
To find h, Substitute values for sin and o. O is EC, Opposite the 23° angle D
<em>0.3907311285 = 1.3/h</em> multiply both sides by h
h(0.3907311285) = 1.3 divide both sides by 0.3907311285
h = 1.3/0.3907311285
3.327096065 = h, the length of the hypotenuse, DE.
Answer: { 3, 8, 12, 43, -14, -25 }
greastest---leastest
Step-by-step explanation:
Answer:
5
Step-by-step explanation:
Pretty self-explanatory
Well 106 divided by 7 is 15 so 15 times 7 is 106
You subtract 5 to the other side so it'll read -6n=-4 then divide -6 to the other side and it'll be 2/3
