Answer:

AOC = 20 degrees

Step-by-step explanation:

We know that FOB is 70 degrees, and COF is 90 degrees. So just add 70+90 and get 160 degrees. Then you subtract that from AOB which is 20 degrees.

If AABC = ADFE determine the values of x and y.
natita [175]

8y - 5 = 99 \\  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: 8y = 99 + 5 \\ \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  8y = 104  \\ \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   y=  \frac{104}{8}   \\ \:  \:  \:  \ \:  \:  \:  y = 13

\:  \:  \:  \:  \:  \: 2y + x = 38.4 \\ 2(13) + x = 38.4 \\  \:  \:  \:  \:  \:  \: 26 + x = 38.4 \\ \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   x = 38.4 - 26 \\ \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  x = 12.4

Find the distance between the following coordinates: I(-a,b), J(a,b)
olchik [2.2K]

Answer:

2a

Step-by-step explanation:

using distance formula:

√(x₂-x₁)² + (y₂-y₁)²

putting values,

√{a-(a)}² + {b-b}² = √ {a+a}² + 0²

= √(2a)² = √4a² = 2a

Hope this helps:)
