7 0

Answer:

solve for x

x=2

Step-by-step explanation:

x2-20x-17=-53

reorder like terms x2= 2x       2x=20x-17=-53

collect like terms 2x-20x=-18x           -18x-17=-53

move constant to the right hand side and change its sign   -18x=-53+17

calculate the sum -53+17= -36         -18x=-36

divide both sides by -18  -18x÷-18= x        -36÷-18=2

x=2

Find the measure of angle K.
BabaBlast [244]
Every triangle have three angles that add up to 180°. With this information, we can find out the missing angle.

The sum of three angles should add up to 180°. 

148° + 11° + K = 180°

Where k is the missing angle.

Solve for K.

Combine like terms.

148° + 11° + K = 180°
159° + K = 180°

Subtract both sides by 159°.

159° + K = 180°
159° - 159° + K = 180° - 159°
K = 21°

So, the missing length is 21°.
