Answer:

c = 6√2

d = 12

Step-by-step explanation:

The sides of any isosceles triangle (opposite the congruent angles) are congruent. Hence c = 6√2.

The hypotenuse of an isosceles right triangle is √2 times the side length, so ...

d = c√2 = (6√2)(√2) = 6·2

d = 12

If you don't believe that, you can always use the Pythagorean theorem to find d:

d^2 = (6√2)^2 +c^2

d^2 = 72 +72 . . . . . . . . . since c=6√2

d = √144

d = 12

Bill works for a large food service company. In one hour he can make 19 sandwiches or he can make 40 salads. Bill works 7 hours

wolverine [178]

Answer:

$x=216 salads$

Step-by-step explanation:

One Hour:

Salad=40

Sandwich=19

Total work time $T=7$

Generally

Time to make 30 sandwiches is

$T_s=\frac{30}{19}$

$T-s=1.6hours$

Therefore

Bill has 7-1.6 hours to make salads and can make x about of salads in

$x=(7-1.6)*40$

$x=5.4*40$

$x=216 salads$

Suppose cos(a)=.325

tatyana61 [14]

The value of tan a is 2.9098

Explanation:

The given value is $\cos (a)=0.325$

Now, we shall find the value of sin (a), using the identity,

$\sin ^2(a)+\cos^2(a)=1$

Substituting the value of cos (a), we get,

$\sin ^2(a)+(0.325)^2=1\\\sin ^2(a)+0.1056=1$

Subtracting both sides by 0.1056, we have,

$\sin ^2(a)=0.8944$

Taking square root on both sides, we get,

$sin a= 0.9457$

Now, we shall substitute the value of sin (a) and cos (a) to determine the value of tan (a) in the identity $tan (a) =\frac{sin(a)}{cos(a)}$

$tan (a) =\frac{0.9457}{0.325}\\tan (a) = 2.9098$

Thus, the value of tan (a) is 2.9098
