Answer:
30°
Step-by-step explanation:
A triangle always adds up to 180° so since one side of the triangle is already 90°, that means the other two sides add up to be 90° as well.

Since the polys are similar, the following equation of ratios is true:
7/8 = x/3. Cross multiplying produces 21=8x, and so x = 21/8 (answer)
the answer is three divide by ten
9.8(k+9)−5.7
Distribute:
=(9.8)(k)+(9.8)(9)+−5.7
=9.8k+88.2+−5.7
Combine Like Terms:
=9.8k+88.2+−5.7
=(9.8k)+(88.2+−5.7)
=9.8k+82.5
Answer:
=9.8k+82.5
