He spent 560. Just multiply 70 with 8
Answer:
<u>Longer leg = 5 feet</u>
<u>Shorter leg ≅ 2.89 feet</u>
<u>Hypotenuse ≅ 5.78 feet</u>
Step-by-step explanation:
Let's recall that this is a special type of triangle where the three angles measure 30 degrees, 60 degrees, and 90 degrees. The ratio of the sides is 1: √3 :2. That is to say, the hypotenuse is twice as long as the shorter leg, and the longer leg is the square root of 3 times the shorter leg.
Upon saying that, we can find the length of the legs of the triangle given:
Longer leg = 5 feet
Shorter leg * √3 = 5
Shorter leg = 5/√3 = 5√3/3 ≅ 2.89 feet
Hypotenuse = 2 * Shorter leg
Hypotenuse = 10√3/3 ≅ 5.78 feet
Answer:
Step-by-step explanation:
To write the factored form, multiply a*c from the standard form . Here it is 4*1 = 4.
Then find factors of 4 that add to b=-4.
4: 1,2,4
-2+-2 = -4
Split the middle term into -2x+-2x and factor by grouping.
