Last month, Mishika, a secretary in a large university, complained to OSHA that the air in her office made her sick. She could see green mold in the ventilation system. She had been treated for breathing problems 4 times in the past year. An OSHA inspector arrived at the plant this morning to provide which level of enforcement? a. Imminent danger
b. Serious accident
c. Employee complaint
d. Target inspection
e. Random inspection

Employee complaint

Explanation:

From the question, we are informed that last month, Mishika, a secretary in a large university, complained to OSHA that the air in her office made her sick and that she could see green mold in the ventilation system.

We are further told that she had been treated for breathing problems 4 times in the past year. An OSHA inspector arrived at the plant this morning to provide employee complaint. This is because of Mishika's complaiint.

bd = 9 cm

step-by-step explanation:

in a 30°-60°-90° triangle, the ratio of side lengths is 1 : √3 : 2. that is, the longest side (hypotenuse) is twice the length of the shortest side.

all of the triangles in your geometry are 30°-60°-90° triangles. ac is the hypotenuse of δacd, and the short side of δabc.

the short side ad of δacd will be half the length of ac, so 3 cm. the hypotenuse ab of δabc will be twice the length of ac, so 12 cm. segment bd is the difference of the lengths ab and ad, so is

bd = ab -ad

bd = 12 cm - 3 cm = 9 cm

comment on side length ratios

you can figure the ratios of side lengths in a 30°-60°-90° triangle by considering the trig ratios of the angles. or you can figure the length of the altitude of an equilateral triangle of side length 2 using the pythagorean theorem.

answer; /// that is so (false);
