Answer:
The answer for ∠B = 68°
Step-by-step explanation:
Total angle in a triangle is 180° so you can just substract ∠A and ∠C from 180° :
∠A + ∠B + ∠C = 180°
90° + ∠B + 22° = 180°
∠B = 180° - 90° - 22°
= 68°
200 hours.
It’s 10km for every one hour
Divide 2000 by 10 and you will be left with the number of km for every one hour.
Answer:
The discriminant is 40
Step-by-step explanation:
First, rewrite the equation as
so that the equation is in the form of
. Thus, the discriminant is
. This tells us that since the discriminant is greater than 0, then there are 2 real solutions.
