Answer:

  7.2 volts

Step-by-step explanation:

3% of 240 is ...

  0.03 × 240 = 3 × 2.40 = 7.20

The maximum allowable drop on a 240-volt circuit is 7.2 volts.

A 5 hour and 25-minute flight begins at 9:40 at what time will it end
motikmotik
Your answer is 3:05.

 You must add on to 9:40. So what I did was 9 + 5 = 14.
14 - 12 = 2.
So far it's 2:40.
25 minutes + 40. = 65.
Well there are 60 minutes in an hours. So 65 would be equal to 1H and 5min.
Now take that 1 hour. Add it to 2.
3 hours. And take your 5 minutes.
There! 3:05

use the pythagorean theorem to find the missing side length. 2 write sin, cosine, tangent of each angel.​
Harlamova29_29 [7]

Answer:

1) x=5\sqrt{3}

2) sin(a)=5\sqrt{3}/14

sin(b)=11/14

cos(a)=11/14

cos(b)=5\sqrt{3}/14

tan(a)=5\sqrt{3}/11

tan(b)=11/5\sqrt{3}

Step-by-step explanation:

 The Pythagorean Theorem is:

a^{2}=b^{2}+c^{2}

Where a is the hypotenuse and b and c are the legs.

The missing side lenght is one of the legs, then you must solve for one of them. Therefore, this is:

x=\sqrt{(14yd)^{2}-(11yd)^{2}}=5\sqrt{3}yd

MEASURE OF ANGLE:

Keep the identities on mind:

sin\alpha=opposite/hypotenuse

cos\alpha=adjacent/hypotenuse

tan\alpha=opposite/adjacent

Susbstitute values, then:

sin(a)=5\sqrt{3}/14

sin(b)=11/14

cos(a)=11/14

cos(b)=5\sqrt{3}/14

tan(a)=5\sqrt{3}/11

tan(b)=11/5\sqrt{3}
