Find the measure of the indicated angle to the nearest degree.
A. 36
B. 30
C. 54
D. 60

54 degrees

Step-by-step explanation:

This is trigonometry. So we are given the adjacent leg and hypotenuse. So we can use cosine(cah from soh cah toa)

We will have to use the inverse of the trig ratios.

Remember!

cos^-1 is not 1/cos(that is sec)

cos^-1(27/46)

acos(27/46)

54.0586701 and so on

Round to nearest degree 54

109 is the nearest whole number/final answer! : )

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
