Answer:
1354
Step-by-step explanation:
The single line marks indicate the two lines have the same length. Thus, the unknown length is 3 cm. 15 mm = 1.5 cm, 25 mm = 2.5 cm. The rest is trivial.
The slope is 5/2.
Explained : By using the rise over run method, find two points on the line (-4, -8) and (-2, -3). You can go up 5 from (-4, -8) and to the right twice taking you to (-2, -3). Convert to a fraction. 5 up, 2 right = 5/2.
Answer:
1/(k^2)
Step-by-step explanation:
Because the k's are above one another in the fraction format, using exponent rules you would subtract the top number exponents with the bottom number exponents (note do not do anything with the letter k). 5-7= -2, and k^-2 is the same as 1/(k^2).
Hope you have a great day and this helps! :)
Answer:
Step-by-step explanation:
∠AEC ≅ ∠BED as vertically opposite angles
- m∠AEC = m∠BED = 1/2(mAC + mBD), angles between intersecting chords
<u>Substitute values and solve for x:</u>
- 4x = 1/2(120 + 2x)
- 4x = 60 + x
- 3x = 60
- x = 20
<u>Find the measure of AEC:</u>
<u>AED and AEC form a linear pair hence supplementary:</u>
- m∠AED = 180° - m∠AEC<u> </u>
<u>Find the measure of ∠AED:</u>
- m∠AED = 180° - 80° = 100°
