All the members of a construction crew work at the same pace. six of them working together are able to pour foundation in 22 hours. how many hours would this job take if the number of workers: increased 2 times

In the diagram below, dab and dac are adjacent angles. if mdac = 25°, what is mdab in degrees? what is mbac in degrees?

Ijust need to see how to do this. so you don’t have to answer all of them just a step by step explanation of one.

The triangle shown has a hypotenuse with a length of 13 feet. the measure of angle a is 20 degrees. and the measure of angle b is 70 degrees. which of the following is closest to the length, in feet, of line segment ac? no need to use a calculator to find the trig numbers. each function is listed below. 4.4 5 12.2 35.7
