Answer:
x = 10
Step-by-step explanation:
to find the measure of angles we first need to find the value of x
The sum of interior angles in a triangle is equal to 180
9x + 7x + 2x = 180 add like terms
18x = 180 divide both sides by 18
x = 10 to find angle measures replace x with 10 in each representative like:
m<L = 9x and 9*10 = 90 and so on
Step-by-step explanation:
-7.1 · 2.3 − 5 + 0.4 + (-1.1)
Use order of operations PEMDAS: parenthesis, exponent, multiplication and division, addition and subtraction.
First, simplify the parenthesis.
-7.1 · 2.3 − 5 + 0.4 − 1.1
Next, multiplication:
-16.33 − 5 + 0.4 − 1.1
Finally, add and subtract.
-22.03
