The difference between the acute angles of a right angled triangle is 72degree find them .
MaRussiya [10]

The 2 angles add up to 90 degrees so

x + y = 90, also:-

x - y = 72 (given)

adding the 2 equations:-

2x = 162

x = 81

and therefore

y + 81 = 90

y = 9


Answer the 2 angles are 81 and 9 degrees

In considering the water quality in and around the U.S., the EPA analyzes critical chemical and physical states: oxygen, nutrien
Karolina [17]

Answer:

wastewater and fertilizer runoff

Step-by-step explanation:

Factors such as temperature, pH electrochemical (redox) potential, and the transparency of air and water can affect the chemical and physical characteristics of ecological systems. This are as a result of activities like climate change, water contamination, and changes in water runoff.

Wastewater and fertilizer runoff causes low amount of dissolved oxygen  in water, which affect biological communities and cycling thereby resulting in chemical and physical states changes.

Given the following exponential function, identify whether the change represents growth or decay, and
cestrela7 [59]

Answer: 97% growth rate.

Step-by-step explanation:

Hi, to answer this question we have to analyze exponential function:

A = P (1 + r) t  

Where:

p = initial value

r = growth or decay rate (decimal form)

t= number of time intervals

A = value after t intervals

Replacing with the values given:

y=3400(1.97)^x

Where the term 1.97 = 1 + r

Solving for r:

1.97-1 = r

0.97 =r

Since the rate is positive, it is a  growth rate.

To determine the percentage we have to multiply it by 100

0.97 x 100 = 97%

Feel free to ask for more if needed or if you did not understand something.
