Answer:

70%

Step-by-step explanation:

I'm pretty sure its 70 because write it as a fraction 28/40 when divide them both and you get 0.7 which is 70. I hope that works

He has 70% of his questions correct.

This is why because 28/40 simplified is 7/10 and I know this is by dividing each number by 4. Also 7/10 and 0.7= 70%

A surveyor in a canyon takes measurements and draws the diagram shown.

Answer:

\approx 118.4

Step-by-step explanation:

We know two sides and the angle between the sides, so we can use the Law of Cosines. Recall that the Law of Cosines states that:

c^2=a^2+b^2-2abcos(C), where a and b are the sides and C is the angle in between.

Let's substitute 115 for a, 178 for b, and 41 for Angle C.

Thus:

c^2=115^2+178^2-2(115)(178)cos(41)

c^2=44909-40940cos(41)

c=\sqrt{44909-40940cos(41)}

c \approx 118. 4
