Answer:
A. 38 degrees
Step-by-step explanation:
That entire angle is supplementary meaning it will add up to 180 degrees. So we are given 52 and 90 because of the right angle. Those together come to 142 then subtract that from 180 and get 38 degrees.
2x+20 + x+40 = 180
The angles are supplementary so they add to 180
a^2=b^2+c^2.
a^2=10^2+17^2.
a^2=100+289.
a^2=389.
a=√389.
a=19.72~20cm.
Answer: 105 meters
Ostrich's running rate is 63 meters/3 seconds. This can be reduced to 21 meters/second (21 m/s).
(21 m/s)*(5 sec) = 105 meters
