I don’t know if you meant b^2 and c^2 or b x 2 and c x 2 so I’ll do both.
If it’s meant to be multiplied by 2, then you do 9^2 + (40)2 =c2
81 + 80 = c2
161 = c2
/2
80.5 = c
However I do doubt it’s that. This means it’s likely meant to be squared instead. In which case, use the following answer.
9^2 + 40^2 =c^2
1681 = c^2
Then square root both sides to get just c (which i assume is what you’re trying to find?)
Square root of 1681 = 41
So your answer would be 41.
Answer:
D. 40 miles
Step-by-step explanation:
If Mark rides 20 miles for every hour and he rides for 2 hours, then just multiply his time with his rate.
20 x 2 = 40
Answer:
The measure of angle E is 45 degrees
Step-by-step explanation:
To get the measure if angle E, we use the appropriate trigonometric ratio
From the question, EF is the hypotenuse since it faces the right angle
EG is adjacent to angle E
so we are going to use the trigonometric ratio that connects adjacent to the hypotenuse
This trigonometric ratio is the cosine
It is the ratio of the adjacent to the hypotenuse
Thus,
we have it that;
Cos E = EG/EF
cos E = 6√26/12√13
E = arc Cos ( 6 √26/12 √13)
E = 45 degrees
