Find the measure of angle y. Round your answer to the nearest hundredth. (please type the numerical answer only)

the measure of the angle is

Step-by-step explanation:

Notice that the unknown angle is opposite to the 4 units long leg of the right triangle which has hypotenuse equal to 20 units. therefore, we can use the arccosine function to find the measure of the angle:

where we have rounded the answer to the nearest hundredths as requested

70,000 + 6,000 + 800 + 30

step-by-step explanation:

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
