Answer:

ZA is acute

Step-by-step explanation:

Here, we are interested in knowing what can be concluded given the information in the question.

Firstly, a definition was given for angles which are less than 90. Afterwards, a given value was set for the angle.

Since the given angle is less than 90, we can identify that that the value of the unknown angle is acute, which gives our answer

What is w(53)is equal to

oksano4ka [1.4K]

Answer:

Step-by-step explanation:

The question is slightly ambiguous. The problem is, do you find the first 40 hours using 10x and then the second equation using x >40. I don't think so, but it should be made clear. It turns out that the first 40 hours does equal 400 so that you can use the second expression with no worries.

w(53) = 15(53 - 40) + 400

w(53) = 15(13) + 400

w(53) = 195 + 400

w(53) = 595
