Answer:

x = 20°

Step-by-step explanation:

We know that the big angle is 90°, due to the marking on the diagram. So, we make all the angles add up to 90°. Now, we can make the x stay on one side and solve for the value.

Answer:

x= 20 degrees

Step-by-step explanation:

We know the sum of the three angles adds to 90 (because of the box in the corner)

x + 2x + x+10 = 90

Combine like terms

4x +10 = 90

Subtract 10 from each side

4x+10-10 = 90-10

4x = 80

Divide each side by 4

4x/4= 80/4

x = 20

D. One holding pen uses 500 feet of fence
inn [45]

9514 1404 393

Answer:

  500 ft or 166 2/3 yards

Step-by-step explanation:

The tie wire is (100)/(100 +500) = 1/6 of the total length of wire used. If 1000 yards of wire is used, 1/6 of that amount can be expected to be tie wire. That is ...

  (1000 yd)/6 = 166 2/3 yd = 500 ft

Solve the equation 4s2+32s=60 by completing the square
lord [1]

Answer:

s = -4 ± √31

Step-by-step explanation:

Given 4s^{2} + 32s = 60

divide by 4 throughout

s^{2}  + 8s = 15\\s^{2} + 8s + (\frac{8}{2}) ^{2}  = 15 + (\frac{8}{2}) ^{2}

 (s + 4)^{2}  = 31\\s + 4 = \sqrt{31}

s = -4 ± √31
